My dad is in love with the old mopar spray 0318039AB. I guess the formula has changed, which he doesn't like. Any thoughts what might be a good replacement? He like the foaming aspect of the original.

Thanks!

Kroil is my 80 year old dads favorite
That stuff works!!!
Have to google it and look around --not sure where the heck he gets it but wow! I have seen it do amazing stuff

Cyclo WAS one of the best in the past...

PB Blaster is what I've been using of late...


(Now I see there's some 'new' stuff out there that contains moly...)

I also like Kroil but I bought some Liquid Wrench 5 years ago and it worked as good, maybe better.
Like the Mopar penetrant, it also foamed up.

For all purpose penetrant, lube, and protection...

JB-80 by Justice Brothers

Once you break the bolt loose you need to lube it while unscrewing it or it could break on the way out. Also works great for lubing any metal to metal sliding surfaces and resists water washing it away. In my old job I sold it to huge gate company and their customers would call and Demand JB-80 to maintain their gates

For years we also sold it to many Chrysler dealerships that could have just asked for the Mopar stuff that was also on the shelf.

Works as good as anything and it doesn't smell like cancer (PB Blast'r). Kroil for the win.

Dam...

Now, even 'PO' has to be 'PC'???

"Homemade Penetrating Fluid, How to Make Your Own" with unscientific test showing better than store bought.

The WD-40 "Specialist" Penetrating oil seems to work pretty good. At least better than the regular WD-40, I would say it is as good as the PB Blaster I normally use?

I ordered a couple of the recommendations here and will let him try them to see what he thinks. I appreciate the feedback. I collect chrysler's from 57-65, a lot of that stuff hasn't moved in awhile!

I tried it with non synthetic trans fluid and it wasn't very good, for me at least.

Kroil is the best i have used. decent results with pb blaster too.

Works for me too.

Everything works to some degree, but Kroil is the best I've seen.
We tested it at work by letting collars rust up on steel shafts for 3 months. 5 penetrants were tested and the Kroil won.

I've been using PBlaster for several years. But heard nothing but good things about Kroil from a couple guys around town who swear by it.

When we sold JB-80 to a PBlaster user, they never went back.

JB-80 just isn't in Home Depot or Pep Boys, etc. We primarily sold it to industrial accounts, dealerships, and repair shops.

Funny , we had Kroil at work and I was less than impressed with it, we also had a penetrant called GLOBO and it was the best I have used ... I still have a couple of cans stashed here at work. At home I use PB with very good results.

That said I just ordered a gallon can of Kroil because I picked up a WW2 USP Colt in original condition and it has been recommended to soak it in kroil to clean up the PATINA it has before oil it down for storage.

We used PB at work along with Castle for years.PB you can just about use water.Ive been using the WD40 penetrant thats new.Works good so far.We did use Zep at work and it was fantastic.It had teflon in it and beat all others we used in 30 years.Rocky
