Specifically something like a hood or roof. The roof on my car has been painted with spray cans and has some patchiness to it. My friend says using a catalyzed 2K clear like Spray Max 2K glamor clear will make it uniformly glossy. Another friend used it on the dash of his '50 Chevy and it looks good but I'm concerned how well it will work on a large flat panel and if I’ll just end up with a shiny patch mess? Will it make a worthwhile improvement?
My modern daily driver had the clear coat turn white.I scuffed it down,and shot clear over it.It darked up the paint again,but did nothing to hide that there was damaged paint.It looked better from 15 feet.In the end I sanded it all reshot the base coat color then shot 2k clear.It ended up looking pretty good.I found that it takes 4 coats of clear to get gloss.At the 3rd coat it was still dull,and I was low on paint.The 4th made it all flow,and I got the gloss.If you do a large panel like a hood count on using 2-1/2 to 3 cans of clear.
