RE: need a correct answer about fuel proof paint.
I know that the water based stuff is improving. And I know it does hold up in the short term. But if you fly one plane regularly then raw fuel is constantly getting to the finish. There is at least some raw fuel in any exhaust deposit. After a year or 2 of constant use the water based stuff will start to lift. As kdheath noted above with his raw fuel test. I have yet to see any water based stuff, Nelson or otherwise, that can really hold up to frequent use over long time. By that I mean on the order of 3 to six flights per day and 1 to 3 days of flying every week all year long. I think most modelers put 50, maybe 100 flights on a plane in a year, but 600 or more is not unheard of. So that is what I meant when I said water based has no chance.
