Last car I did in a metallic was in oem maroon whatever the name. Yes it was done in a shed with poor light cheap gun, and not really adequate compressor. Not that I am that skilled but I am lucky. The metallic went good. The single stage is cheaper by enough to make me think about it. I figure the base in the metallic will go better. Today I have a lesser compressor, same cheap gravity guns, and still poor light! Probably need to do the bc/cc.. If it is not right, wife will kick my *** till it is right. lol
