stripper?

r
I truly know you a Mopar Body Work Genius, but I have two questions. First, I use paint stripper all the time, so I am not really disagreeing with you. If you use 80 grit in a DA and take it down to bare metal, How are you not going to see the Bondo? And does a DA with 80 grit cause enough heat to cause a problem? I bet the surfaces get hotter in the sun on a hot July day.
How much sanding of the metal next to an area that you already have the paint sanded off of will you need to do. You will change the thickness in spots before all the paint is removed.

A hot summer day does heat the metal but the heat is uniform. Darts and Valiants including sport body styles have body lines that go down the sides. They are not round like other makes and models. Round always stays round. It may get rounder but it is not noticeable as easy as a flat panel.

Flat panels will not stay flat. and you will distort the lines and take the edges off. I do go over the panels with a DA to scratch the metal for primer but never sand the lines. Early Coronets and Chargers have lines that will disappear on the quarters when sanded. And sanding the paint out of the scallops and scoops is very hard to do.

One other ting is that a sanded car will rust when taken to bare metal. A paint removed you can leave set for years and no rust. This Demon below was stripped in 1999 aftre metal prepped it sat in a trailer since. It only has surface rust where it was touched. fingerprints? You can use this info or not. Most body shops have one thing in mind get it painted and get paid. Its not their car that they will be looking at in years to come. Never paint strip any seams.

There is a place near me called "ready strip". I guy I know had a 69 camaro dipped. After it was painted white years down the road all the seames turned yellow. Ray Barton had a Dart done. He ended up not using the body. Call Bartons and ask him why. Prep is the most important thing when painting the car. Removing all the old material is the first and most important part of that prep. Sure you can use primer filler and remake all those lines or feather edge that old paint. Its just not the proper way unless your going for thickness.LOL

I only Paint strip the outer sheet metal the rest is media blasted to remove the rust. Never blast the inside of the roof or quarters. if you do the panels will warp. I always blast the rockers and lower body after paint stripped to remove and small rust pits. Then apply Acid and then wash prime. then primer surfacer. Good luck on your project.
