Current "wisdom" on wax / grease cleaning?

[Jacob]

Planning to start working on the body soon and in looking at past posts I see where an initial washing and cleaning with wax / grease remover was done...is this still the thing to do prior to any sanding or knocking down the seams? thanks in advance!

Miller says No, and Kleiner says Yes.

I chose yes to have piece of mind.

If you drill the pilot holes in the body for the passenger roll bar, you'll have those holes available later on if you ever want to add the passenger roll bar. Do it before the degreaser.

Later add body filler to fill the holes. Look from the bottom of the body to see where they are marked.

I was told to use wax & grease remover by the paint store and a professional painter. So i did!

I worked in an auto body shop for a few years, in high school and college, as a painter. We painted everything from high-end cars to industrial machinery to sailboats to garbage cans. The one common denominator was that we did no surface prep without first cleaning the surface with wax and grease remover. The doomsday scenario was that if you skipped that step, you ran the risk of grinding some surface contaminant that caused "fisheyes" into the substrate, and you'd have a hell of a time fixing the problem after pushing that contaminant deep into the substrate. I can't speak to what anyone else has had success with, but it seems to me that if someone successfully skipped this step, they are probably doing something else, prior to sanding, that accomplishes the same thing.

EDIT: There is nothing magical about wax and grease remover, and I could think of 10 other things I would use in its place if I needed to move forward on a project, all of which would be far cheaper than whatever I paid for the last gallon of PPG DX440 I bought.

Go to the local hardware store like Ace and get a can of NAPTHA and use the blue shop towels. NAPTHA is the active ingredient in almost all prep cleaners and it costs a 1/3 as much.

thanks all!
