Curious- base coat vs acrylic urehane for base

Yes, single stage can be tough to flow out nice without getting some mottling (Non uniformed) in the metallic.It can be done for sure. Base goes on easy and the clearcoat is good if you need to do a repair on a panel. You can sand your spot repair and the rest of your panel in 1000 Grit. Then blend in your color and clear the whole panel. I think single stage is good for solid colors. I do it with Black cause I think it looks Blackest .
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
