Finishing a RR factory made cowl after making some mods and bumps and fitting to the firewall, I sanded off the glaze on the outside gel-coat, wiped all surfaces, inside and outside,with acetone and applied Smooth Prime. The Smooth Prime adhered to the gel-coat and the new fiberglass as advertised. The inside rough fiberglass, 23 years old, had the Smooth Prime shrinking, cracking and flaking off in small and large pieces. Some areas adhered quite well; others could be plucked off; others fell off. What's going on? Any suggestions for Smooth Prime remover? MEK, acetone, alcohol, water, paint thinner, and paint stripper have no effect on cured Smooth Prime.
