Spraying solid colours - avoiding dry patches and overspray
In all the above, the intention is to prevent any direct spray from the gun falling onto panels which have dried too much to absorb the overspray. With a little forethought dry patches can usually be avoided altogether, or kept in places that are small and hence need minimal polishing. The correct grade of thinners and activators is important. Fast thinners etc. will be ideal for a single panel on a cold day, but will make a respray barely possible. On the other hand, using a slow thinner or activator on a cold day may produce runs or sags easily. Balance the speed of thinners and activators with the repair in hand, or take advice from your paint supplier.
