Hi guys, have bin playing round with my infusions for a while now, tried the spray tack method and as expected it had a negative impact of surface finish. I wasnt too worried as I plan to clear coat the parts anyway.

Nevertheless I plan to try the gelcoat method. What are my advantages of using the GC50 epoxy compatible polyester gelcoat apart from it being cheaper than epoxy gelcoat? UV stability I understand, polishable etc...

Is it worth using a gelcoat if i plan to clear coat the part?

If I try, I am not really looking forward to spraying it in. Can a nice surface be achieved by just brushing the gel on? Or will the brush marks be visible in the surface, in which case it kind of defeats the purpose.

Cheers

Thanks guys! Joe that is what I thought, would be too difficult to get an even coat, non blurry etc..

And Matt, that is EXACTLY what I have been waiting for, good on ya, It sounds highly promising and I will be placing an order shortly.

Cheers
