Eastwood brand self etching primer.

Not to talk you out of your choice, there are a few trains of thought on this topic, but are you planning on wet sanding at all Boyg, tons of problems can show up if you plan on using self etching and wet sanding! Let me know, JR

I was just going to use it as a first coat to help the building primer stick to the car. I will wetsand the rest of the primer coats.

Say bg just one note,make sure that etch prime is compatible with what ever paint system that you're planing on spraying or you'll have all sorts of problems. Also when you say primer remember that there are difference between a primer and a primer surfacer and primer sealer. Etching primer and primer sealer are not to be sanded,its meant to be used as a wet on wet system. A primer surfacer is meant to be sanded then topcoated. So if you plan on spraying the etching primer and a surfacer over that like I said make sure its compatible. Hope this helps.

Hmmm, this is getting complicated. Maybe I should get a "how to paint" book. Anybody have any suggestions. The last thing I want to do is use incompatable primer/paints and ruin a few hundred hours of work and thousands of dollars.

I didn't mean to open a can of worms, but if you are wet sanding and break through to the self etching it will soak up the water like a sponge, and that means a high chance of rust starting under your new paint, if you are careful I guess it could be OK but it's still chancing it. Let me know if you have any questions, I'm by no means a pro but I have picked a few brains in the past..JR

If the self etching primer is so hard to work with, do I really need it. Will regular primer work for me. Most of the rusty/pitted panels on my car will get eastwood rust encapsulater or POR-15, so I'm not worried about getting the primer to stick there.
