best practice

[Treeslayer]

it has always been the plan to sand off the repaint some one did on this pick up. do you think this is a reasonable plan or am i creating unnecessary work?
its unknown what it is, it is a dull light blue, no shine at all. it is hard, i was surprised, its hard to sand. since i dont know what it is, the plan is to get down to factory paint and seal that with epoxy. or would you just break the surface? other than damage and suspect work of course.

Generally guys will either sand what's there, or strip to metal. If the existing paint looks good, no peeling, bubbling, etc, then a good thorough sanding is OK. If you are going to the trouble of sanding the refinish job off then it's just as easy to strip it. If there is any doubt, strip it. You can get stripper discs that fit on a 4 1/2 grinder that make short work of stripping paint. Average car you can strip the exterior in less than a day.

I always try a razor blade first. It is the cleanest way to strip if it works.

Chris those discs, i bought a couple i thought were stripping discs, they do very little so i must have got the wrong ones.
we are about to pull the body out of the shop, im gonna start with a 8" rotary and see how it goes. i guess if i get to bare metal, all the better.
the blue is peeling in spots, factory black is shiny under those spots so i suspect dude didnt do a very good job sanding.

we did that on the filler. the paint is very hard, it was not fun. perhaps i need a better heat gun. thats the third one in five years lol. i use them a lot working on saws.

These are the ones I've been using for the past 5 years or so. I can promise you they will remove paint quickly.

Try it without heat. It often times works better. Blades have to be sharp….

3 hours, we are close to bare metal. damn bondo is every where. dude dulled most of the body lines with it. its only little dings, he didnt need all that.
seems like the 87 factory paint comes off easy, the 86 patch i welded in, that stuff is hard hard.

through out this, i am quietly wondering what i will run into on the cab. i know he patched the cab top, he said he did.........i just wonder how badly......

 

[Treeslayer]

i tell what, this project here is a very good example of why we should epoxy before filler.
i will have some spot blasting to do.
