You put fisheye elimiator in the base?
Most manufacturers state flat out "do not use fisheye eliminator in base"?
Dupont only says "not recommended"..... it usually = Bad News.
With most products, when spraying wet on wet (I'm talking SS and Clear not BC), once you add fisheye eliminator you need it in every coat. HOK is the only one I know of that isn't needed in every coat.
If you get fisheyes in base just adjust your spray technique and spray a little less wet until the craters are filled in.
