Cruz, you don't need to use urethanes to accomplish a good paintjob, you have already shown us how great your work is just by sticking with the basics. No disrespect to Jimmy but if you look at that Merc, the panel lines are completely gone. To me, the urethanes are way too thick and yes, I am gonna hear some people suggesting that if you thin them and shoot them the right way they can certainly be used. I know of quite a few people that use them but 1 out of 10 have the trick mastered, the others just have an idea.
