followed everything to the letter and painted bottom today...used the no sand primer but I still did some sanding to scuff it up. My concern is this...The first coat has nearly dried and in little spots its got alittle cracking..Is this normal for the first coat? Using the petit Hydrocoat ablative paint and 2nd....Is the No sand primer supposed to be almost waterlike? not in color but consistency? There was no wax on bottom anymore..that Im sure of
