The stuff is about $29.00 a gal here at Harbor Frieght and it doesn't go very far concerning how many rusty parts it will derust, but it does work well when fresh. I'd use a slightly oversized length of PVC pipe to hold it for a drive shaft.

I had been paying $25/gallon at Summit as that was the cheapest i had found.

last time I was at my local autozone i noticed they started carrying the gallon bottles for $19.99....previously they only had the quart containers for $9.99. cheapest i have ever seen it.

I calculated it out before I soaked my driveshaft. The shaft takes up most of the volume of the PVC so you don't need much EvapoRust at all. If I remember correctly, you only need a little over a gallon to submerge the driveshaft using 5" PVC.

you can use wood bleach also to remove rust. about $5 for a little plastic tub and will probably make 200 gal. use about i tablespoon per gal.

i've seen it around the internet for 70 to 80 bucks plus a stamp for a 5 gallon pail

There's some more good stuff about drive shaft resto in this post (about midway through the post). I think that he did his before RPM was available though.

I used 1 1/2 gallons in a 4" piece of pvc pipe let it soak for a week. Cost was 19.99 a gal @ the hardware store. I will try and post some pictures.

I used a heat gun. It took a long time to heat it up but it got the job done. Putting it out in the sun would work too depending on the time of year.

Not much Evaporust at at, as was said purchase a PVC pipe, and very little volume around it when submerged. Used a 2x4 to submerge it and stood it up in the corner for a couple days.

I used it on a few bikes i restored, mostly the chrome parts, haven't tried it yet on engine/car stuff yet. works real nice on chrome, usually between a teaspoon to tablespoon per gallon is all you need for delicate stuff like chrome or items that have paint. You can probably go heavier for cast iron stuff. Here is a link to the musclebike forum where i learned about it. I got mine at DIY/ACE hardware for like $5.

Hi everyone,

When we coated the driveshaft with RPM on Project Valiant we used a heat gun( I bought one at Harbour Freight for $9 on sale) and started at one end and slowly worked toward the other end. You can turn the driveshaft as you go to keep the shaft warm. Works good with two people but one person and saw horses works also. On a smooth surface you will probably notice some brush strokes but they can be handled at the end since you'll probably want to use a towel and a little heat to smooth out any brush strokes. Normally the shafts have a little sheen which can be achieved with a clean cloth towel once it cools.

At the end of the day you are not going to have a lot of build up of RPM on the part for protection. In fact if you really apply a lot then it changes the appearance and could appear cloudy. We have actually melted RPM and dipped parts. You have to use the heat gun and brush to remove excess or it could be too thick. Just ensure that you have your part completely covered for best protection. Since it goes on glossy this should help verify coverage. A final pass with the heat gun allows the RPM to flow out and most brush strokes disappear on their own.

I have used a similar technique on a late model K frame where I wanted to do both sides. Dave swapped the white Challenger over from the oil based product used in 2008 to RPM in an afternoon on the lift. It was dramatic how it changed the look of the car and got rid of that oily residue.

All great questions and a great idea on the PVC pipe to soak the whole shaft.

Must be working for me because i'm a member. Anyway if you do a google search you will find a lot about it, keep in mind i was using it for chrome plated parts, so not sure how and to what ratio to mix if your going to do something like a drive shaft or cyl head. Its cheap enough to experiment with at around $5.
