I use HOK over PPG DBC products alot. Before I but the HOK over the DBC I always spray one coat of DBC 500 blending clear over all the parts, then,before I clear I always spray anouther coat of DBC 500 blending clear over all the parts, then I use PPG DCU 2042 clear.
I have not had any trouble yet !!! /ubbthreads/images/graemlins/ohwell.gif
