Later in the thread, maybe it was part 2 of the thread, I don't know it's been a while, Brightside Marine paint is mentioned. At $34 a quart vs. $8 for the Rustoleum/Tremclad it's a but more, but supposedly it covers faster. About 3 coats gives complete coverage where as the Rustoleum takes at least 5 or 6.
Sift through the pages and you'll find a few good pics, but there was one car that was actually taken with a good camera (I guess it's hard to find someone with a good camera in a "paint your car for $50" thread) and it was mirror-smooth. The reflection of the guy holding the camera was flawless.
I found out Marine West, who carries the Brightside line, is about a mile away from home.
But first, must fix rust...
