I'm reading that epoxy primer is very difficult to sand. Is there a more modern brand that is sandable weeks or months after appllication?
You may think your shop is dry enough but, it's probably not. Also anytime you touch it with bare skin it will rust. Once you get it stripped I would go over the entire car with a DA and 180 grit to make sure any starting of flash rust is gone.yes, i am stripping the whole car to bare metal.It's about half done and i've been working at my leisure for about 3 weeks and will prime it when finished. Bodywork and high build sometime down the road.My shop is very dry so the bare metal is fine.
You have to monitor the relative humidity but rust starts immediately in most cases. Bare metal needs to be resanded after 8 hours if it is not protected. That is what the paint manufacturers recommend.yes, i am stripping the whole car to bare metal.It's about half done and i've been working at my leisure for about 3 weeks and will prime it when finished.

House of Kolor had a nice sanding epoxy. It has changed but I'll bet it didnt get harder to sand. Get into the Southern Polyurethane site. Lots of discussion on there and call Barry. He runs the show and will talk to people. I hear lots of good things about his products and service. https://www.southernpolyurethanes.com/So many different methods, tx guys but back to my original question .... has anyone used a modern epoxy primer that is easy to sand?
What paint system are you going to use? It is generally best practice to stick to a single paint line. Sikkens is what I spray every day of the week. They have a epoxy primer that can be used as a wet on wet sealer or sandable primer surfacer.

Call Southern Polyurethane. They'll give you some accurate answers.
I love SPI paint, but I have to make a confession to keep someone else from screwing up like I did a week ago. It has been several years since I bought a pile of stuff from them. I called and made an order, and it arrived quickly and well packed. I noticed the round gallon cans of epoxy and 2K primer had plastic rings on the tops to prevent the lids from being accidently knocked loose. When it came time to use the epoxy, I got a flat screwdriver out and tried to get the ring off by prying it loose from on top of the lid. It wasn't budging, so I called and asked Barry what the trick was? He said I was doing it right, to just use a screwdriver to pop it right off. Well, after I had pretty much destroyed the lid of the paint can, I figured out that you do it by sticking the screwdriver up under the ring on the SIDE of the can.....not on top of the can! I had to go down to Home Depot to buy a new gallon paint can to put 3 1/2 quarts I didn't use in! Dumbass!.......lol.Hard to beat Southern polyurethanes epoxy and other products. Their epoxy is sandable.
