Hello all,
I'm doing some fiberglass layups and am having problems with the gel coat.
I am spraying it with a regular (cheap) spray gun which has had its material
nozzle drilled out and the pin filed down. This was to allow the thicker
gel coat to flow through. Its still slow but usable.
How do I prevent the pin holes? I get many of them; and while the part is
still usable, I'd like to know what I'm doing wrong.

Thanks,
Arnold
