Tail Gunner, was that sprayed or rolled and tipped?
My two cents is that both Imron and Awl Grip are two part polyurethanes, both when applied per manufacturer specifications are excellant products. DO NOT skip steps, or use some primer under them that is not compatible with the topcoat.
I have painted a lot of diesel engines before shipping them out to boatbuilders the likes of Bertram, Viking etc with Imron and it was a very good finish. I also painted a 1970 Caravelle for a buddy using Chrome Yellow color Imron, I got some dry spots in it due to my lack of gun practice, but he told me the boat has changed hands and is now rotting away in a trailer park in Florida sun but the paint still gleams like 1994 when I shot it on.
Imron is a DuPont product and availible anywhere DuPont auto refinish products are availible. Awl Grip is not marketed towards anything but the marine/yacht refinish market so finding a dealer may be harder.
I was going to use Imron on my 15 footer (after the EasyPoxy I used three years prior was chalky and scratched too easily everywhere) and the gallon of snow white Imron with all the hardeners etc was $225, they offered me a generic DuPont product from their "Nason" brand of paints. The paint was "Ful Thane". It was $107 for the gallon. The guy said the Imron was a ten year paint, the Nason was a seven year paint. It was half the price, and my boat stays covered in the shade on a trailer. Guess which I bought?
