Today (7th July) was a freak day weather wise with temperatures at 26+ Deg. Celsius - this effected my gelcoats and coupling coat.
During the second gelcoat, I found that globules/small pieces were forming in my mixing pot, fortunately these are mostly on the flange area.
Even with less catalyst, the coupling coat globuled in the same fashion at a later stage of putting it all down. Regardless, I got the CSM to conform well to the 'pattern area', and most of the globules are also on the flange.
So the coatings on the 'pattern area' are 95% OK, however the flange bit is a little bumpy (5mm dia max circular bumps). What's my chances of a decent mold for resin infusion (no post-cure for mould, nor in-mould post-cure for laminated CF)?
I will be doing the final tooling resin process when it's slighly cooler tomorrow. Would the process work without any catalyst?
Thanks guys!
