GRP pin holes

RobertPW · Saturday at 8:00 PM

Hi all

Had a go at GRP-ing my shed roof and got caught out by weather on about 1 square metre. This section has hardened but has pin holes in the top coat.

What is the correct way to rectify this? Sand the affected area, add resin then re-top coat?

Or is more matting required once sanded?

Any help much appreciated.

I do not know the answer but I would expect the gel coat to fill pin holes. Hopefully someone with more experience will be along soon
