Thinking of spraying a track car with single pack paints as I've had good results on panels before but im not setup for 2K paints. What im wondering is can i paint my car over a few weeks and then take it to a bodyshop to have a 2K clear put on? I'll probably do a test piece to see how the paints and clear react and if they seem ok is there any problems which might show up later such as cracking, peeling etc...? I've had small parts clearcoated before in this way and had no problems so im thinking il be ok? Obviously im not after a show car but if i can get the panels looking good before the clearcoat then in theory it should come out well?
