Hi guys I've decided that I need to move from Qualatex balloons to a silicone bladder.
I've got Smooth On rebound coming just because there isn't much available in NZ at the moment.
Its a three part mold and I've built fiber glass shells to go in the mold parts to correctly size the bladder.

I will mess around with some trials but I'm was a little bit confused about the right time to do second coats and joins last time I did this.
I was using dragon skin then and it seemed to go from runny to tack free without a good tack period to second coats and a complex join.

One thing I did learn last time is that acetic cure tube silicone sticks like s*** to a blanket with smooth on silicone for fixing seam flaws.
The idea is to make a thin patch with the smooth on silicone and then glue it on with the cheap tube silicone.

Any pointers would be massively appreciated...Chris

Are you using pre-preg or wet-lay? The non-perforated release film you see in that bike video is really for pre-preg only, where the resin content is already controlled. If you're doing wet-lay, you wouldn't use that film because as you say, you can't remove excess resin.

You could use a perforated release film though? Would have the same benefits that they used it for in the bike vid, but would allow some resin bleed.
