I used this on my top when I repaired it back in 2004.
I applied it with a "schutz gun" or undercoating/bed liner gun.
The shutz gun reproduced the factory texture pretty well.
It's held up great but did yellow a bit overtime.
I ended up painting the top in 2006 with some boat deck paint because of the yellowing.
I used this stuff.
Interlux deck paint. Mediterranean White(# INTYKA184Q).
I only bought a quart because you thin it, it's more that enough.
It's thinned with the Interlux 333 thinner and simply brushed on.
As of today (14years later) it still looks great.
