The PPG dealer sells only PPG, and I put epoxy under everything. It is very easy to spray, dries fast, two coats takes less time than anything else I use. The Dupont dealer sells other brands, but I have no good reason to deal with him. I don't even approach you in terms of knowledge and experience, but what I recommend on this forum is what I use and it has never let me down in the 10 years I have been doing this. I don't doubt that dp 26 will work in this case, since you are familiar with the product, but I do have some doubts about a product that claims it can be used on any surface, anywhere, any place as the spec sheet implies.   [Reply]  [No Email]

If it works for you, fine. To a body shop time is money and you can save time by skipping a step. I doubt if you or your customer will ever be able to tell any difference by eliminating one step, but somehow I am not a fan of do it all products. So I'm going to stick with what I call true epoxy. Of the entire painting process epoxy is the fastest and most mistake free step that I use. It can be coated with surfacer or topcoated in 30 minutes, but time is not that big a factor to me, probably is to you.   [Reply]  [No Email]
