Unimould issues

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!

Unfortunately it sounds like the steep learning curve has commenced Ermm Don't beat yourself up though, I think we have all done it at some point, I know I have. Angry
