Doing a little test and will post results if anyone is interested. I took 3 globs of Splash-zone epoxy (A-788) and weighed each one after drilling them and placing a piece of tig wire thru them so I could submerse them in alcohol and BP93 to see how they held up. I have them numbered as such.

#1. Alcohol, un-coated, weights 55 grams

#2. Alcohol, brushed on one coat of MinWax polyurethane, 55 grams

#3. BP93 pump gas, one coat MinWax, 45 grams

These where placed in glass olive jars on 5-6-14 at app. 2:30pm and after a few days I will remove and weigh each sample again and inspect to see how they are holding up. Here are a few pictures.







Lets see what happen as alcohol is in lots of gas we now buy.

Is BP93 an E10 blend? That's all it took (10% ethanol) for Moroso A/B epoxy to soften up in my intake manifold.

It may not be a weight difference you see as much as a consistency change. The patches I put in my intake that hadn't been "ingested" by the engine had softened up due to exposure to ethanol and were able to be peeled back something like putty, despite all the footholds I'd created on the surface for the epoxy to bond to.

Definitely interested in hearing about your results w/ the coating.

Its being tested in real life on my sons 360 Duster in the near future. I tube all the Edelbrock heads I port but I also smear a light coat of splash-zone over the tubing. He runs alcohol so this will be a good track tested test. I coated his heads.

Brad I'm not sure about BP93 and the 10% alcohol but on the pump for all 3 grades it states "gas may have up to 10% alcohol content". I've been told that the 93 grade doesn't but you know how that goes. I got away from using Moroso AB epoxy when it started flaking off on to many projects.

I was going to try Splash-Zone after the Moroso AB didn't work out, but heard it's not alcohol-proof either.

The only product I've found that seems to hold up to alcohol is Belzona (#111?), but that sh!t's priced like gold and I don't need nearly as much as the minimum purchase amount requires.

That's why I'm interested in seeing how your top-coat on Splash-Zone holds up.

John, how long did these test samples cure before you submersed them in the fuels?

It is easy to check the jokenol content of gas. Get a container, the one I use is a 100ml graduated cylinder but I think any will do. I put 20ml of water and then fill to 100ml by adding 80ml of gas. Shake it up and let it settle. if there is jokenol in the gas it will separate creating very corrosive jokenol-water. If there is 10% jokenol you will now have 28ml j-w and 72ml gas.

Time for some strange results.
I removed the 3 samples last night at 10pm (5-14-14) so they have been left soaking for slightly over 8 days. When I removed then I placed them out to dry till 4pm (5-15-14)
#1 started out at 50 grams, uncoated, and placed in alcohol. today's weight was 50 grams, very good physical appearance, and held up very good when I tried scratching it with a scribe. Alcohol when removed was still purple.

Now the strange results.

#2 started out at 55 grams, coated, and weighed 55 grams
when removed last night coating was somewhat wrinkly in appearance.
sample now weights 60 grams (5 grams more) looks good but is off color, tested great when scratched with a scribe, BUT the alcohol is now CLEAR instead of purple.

#3. Pump gas (bp93) coated, 45 grams entering test
when pulled last night coating was again wrinkly.
weighted 50 grams in today's weigh-in (5 grams more), looked good but off color. both coated samples lost the nice shine from the coating before the test started, responded nicely to the scratch test and probing with the scribe. Pictures are from today.








Really happy with the Splash-zone after being soaked constantly for that long but I may try some ppg clear coat with hardner for the next test.

I did this test years ago and what was strange is all the epoxys I let soak in Alcohol stayed good but JB weld in running engine or AB epoxy would not make 4 passes in w2 pushrod Area on alky and heads had JB weld in the for 100 plus passes on race gas.

Somthing with heat and evaporation in running engine is hard on epoxy.

Try air plane "dope" for wing covering alky nitro Resistant helps buy some time.

Nice test and reporting BTW. I have no dog in this fight. But if someone was to repeat with a variation, based on others comments, I might suggest a non immersion test, with sample in a sealed container, suspended just over the liquid fuel. You might be gaining some protection with the liquids that if vaporized will not provide. Just a thought. I would also attach blob to a typical metal and perform a peel test at end, compared to non fueled blob

I should add to this that track tested results will be available next Winter as I used splash-zone and coating on Matts 10.50 small block edelbrock heads and he runs alcohol.

UPDATE 8-6-14

I just happened to take a look at my epoxy samples today that have been sitting on my work bench in my shop. Number 1 and 2 both look great but #3 the pump gas sample had about a 1/2 inch crack across it. It was the one that weighted more when I removed it from the jar. I honestly expected to see the alcohol ones suffer the most.

BP 93 pump gas here in IL. last I checked had 12% ethanol in it. Mid June when I tested it.
Could be a variable causing diff. results?

Something seems to have changed with BP93. My Duster used to print time-slips until this year and that is why I made the switch to alcohol last weekend. I only had 2 time trials before the rain moved in but I am heading to the track this weekend to try my luck.

So does the Moroso AB hold up to race gas OK ?

Mark I've used Moroso epoxy but I made the switch to Splash-zone. I still have a pac laying around unused. I sealed the tubing on my Sons Edelbrock head and after short use it was peeling away. With Splash-zone you can mix it and apply it (I use Doctor gloves, the thin type you get at Harbor Freight) then you can wet it and really form it to the needed shapes. Goodson sells it in small containers under their brand name and is a really good company to deal with.

Hmmm.......
Well my problem is I have done a lot of epoxy filling inside my old Rat Roaster intake, and I used the Moroso Epoxy.
My engine is a pump gas build, but if it would save the epoxy work, I would use race fuel when I switch to the RR.
Perhaps a coating as mentioned above would help protect the work I have already done!?
Thanks,
Mark

Mark DON'T use the coating that I used. It didn't work at all. Let me see if I can find a link from Darren Morgan as he has done more of this than I ever will. I used to have a clear coat spray can that I used but the top broke when it fell from my workbench.

I can't find it right now but if you do some playing around with this website you may come up with the proper coating.

Any updates on this? I am working on my little max effort iron head 340. I will be using a Holley Pro Dominator with dual 1150's on e85. Problem I have is that the odd port design of the intake in the plenum/runner area lead to some holes when I did the porting. Looking to fix with epoxy but not sure what or if it will work. Trying to avoid the expense of welding but may be necessary if I can't find a compatible epoxy.

I'm currently trying epoxy #526n, its two part, available in black, approx $140/pint, requires two post application cures, 2hrs @200F, 2-16hrs @325F. they quote good chemical/temp resistant specs. It is tough stuff.

I can tell you that the Splash Zone on my heads with E85 only lasted about a year before the majority of it came off at the pushrod pinch. It wasn't any better then JB weld was.

I just tried it again, but this time added a top coat of KBS Gold Standard Tank Sealer.

It is supposed to be E85 resistant, so we'll see how this goes....

I tried this with E-85 and normal fuel system parts in jars of it and after 10 years in the jars none of the items ever changed, the fuel didn't hardly change smell yet (a little but not much). I did not try any kind of epoxy but I have a steel fuel line, a 1968 piece of rubber line, some brass fittings, holley power valve thermo-quad plastic chunk and a piece of modern EFI line, nothing changed in 10 years. People say "well if you get water in it then it is corrosive" I never tried putting water in my fuel and I try to keep my fuel tanks sealed.

Just a side note; you can get different results with the same epoxy if the epoxy is close to or past it's expiration date. Stuck in a glove box, tool chest or shop that has high temps will affect the characteristics of the A and or B part of the epoxy. I have not tried the EA934NA but from all my uses with epoxy, if you have a base material like aluminum with aluminum or iron with iron/steel or wood powder with wood the bond is considerably stronger. If the manufacturer makes a similar product as a liquid and then adds aluminum(for example), use the clear to wet the parts that you are trying to assemble. Then use the aluminum based epoxy. Your results will improve greatly. Also, do not mix different brands of epoxy because they are all formulated differently. And finally, a roughed surface bonds better than a smooth surface. When you use a brass tube insert, makes sure it it clean and scuff with 320 grit in random motions. This also goes for repairs to aluminum. You don't need gouges but if you get to see how the epoxy flows and the bonds are created and then sheared you will understand.
