Since I am planning on flying before external painting, I am attempting to use Poly Fiber UV Smooth Prime to fill in the pin holes in my fiberglass parts prior to spraying a coat of primer and I have several questions.
I can get the pin holes filled by squeeging in the first coat and then rolling on the additional coats.
The rolled on coats have a rough texture and require much sanding to remove the texture. I have tried several different foam rollers and a short nap roller. Some are smoother than others. But, none are very smooth. Any suggestions on to minimize the texture of the dried surface?
When sanding the coated surface, I am unable to leave a white coated surface everywhere. Namely, in some areas I am exposing the filled in fiberglass. Is this acceptable to have these exposed areas? If not, how does prevent sanding through the coating in some areas?
Your assistance would be appreciated.
Thanks.
