Hi all,



i finished my first part today using GC50 gel coat. Poblem is that the part got hazy and on an yellowish side.
What could be the problem? I sprayed the mould with gel coat spraying gun, let it cure for about 4 hours (25º over here) and then epoxy infused. Into the oven, cured at 50º for 8h.
The primarly objective was to fill the pinholes that i allways get no matter how perfect is the insfusion, and that resulted very well! But when i look at the part compared with other with no gel coat is very noticable the difference. The yellow tone i can understand as beeing a polyester gel coat. But the haze is a big problem.
Any ideas for the cause of this?

Thank you!

We don't have any other videos showing the cup gun in use and to be honest, I'm not sure what benefit you would be able to get from a further video.
