chevy paint prep

ericlb · Jan 6, 2015

i plan to paint a 95 chevy truck after i put the right side on it, [long story] now this thing is white, and has the usual gm paint lifting all the way to the primer on the hood and roof, i plan to keep this truck, as it belonged to a good lifelong older friend who ill never see again, now, im not a fan of base coat clear coat because after 4 or 5 years you see all these jobs with the clearcoat lifting and looking like crap,so i plane to do single stage like i paint all my old trucks, what do i need to do to prevent more of the original paint from lifting under the new paint?

Strip it. The original primer is the problem. Follow the prep instructions for what ever brand / type of paint you will use.
Clear Coat is worth using if you follow the instructions. PPG Delfleet or Dupont Imron single stage paints will last for years.

Like Kansas said, strip it. Don't write off base/clear yet just yet only because the factory stuff is crap. I've never had an issue with any base/clear I've applied. It keeps the shine and doesn't chip like the single stage I used on the same vehicle. The single stage has no shine now but the base/clear is still looking good.

There isn't anything wrong with a single stage paint. The only time I use basecoat clearcoat is when it's a metallic finish. Like others said take the truck down to bare metal and put an epoxy primer on it. Keep in mind it will have a recoat window on it so you need to be prepared to put something over it usually within two or three days. More than likely there will be dents or other leveling that needs to be done but I would put the epoxy on first and then bondo where it needs it. Then you could use a filler primer to finish leveling the finish. Epoxy primers don't sand very will. The filler primer works more like sandable rattle can primer. It's just a lot easier to work with. The epoxy primer just makes a better bond to the metal and provides a better seal against rust. Since you don't have a lot of experience with leveling a finish you might use two different colors of filler primer and alternate with each coat. When you start block sanding the primer the different colors will let you know where the high and low spots are so you don't find out when you put the topcoat on. It's called a guide coat.

All good advise so far. I use single stage for solid colors, base-clear for metalics. Clears easily last twenty years and will make future touch ups much easier.
