hi all.
i recently made my first rc boat mould using the unimould system. i used pva for the bottom part of the plug. and easylease and pva for the top half.
these came out fairly well. but not as smooth finich as i hoped. so hours of wetsanding and buffing later..
i put on 7 layers of easy lease. eg60 transparent gelcoat 2 layers as even as i could with brush. 2x 200 glass 1 carbon (240 or zo i believ) and another 2x 200 glass. for the deck half. in the sharp corners i made a fillit of epoxy and thixotr...between the gelcoat and the glass to have the sharp corners evened out. so far so good. al went in super smooth.
30 hours later. i wanted to pull the part.....
i allmost thought i would break my mould. the edges with the fillit where so stuck!.
now i think i put the release agent on and buffed to hard.
heres question 1. i cleaned the mould. put the easy lease on thicker. didnt buff at all. and i read i can wax it. now before i want anything on top of the easy lease. what do i do when i pull it. do i need to clean it completely and stard over with the easylease. or can i just remove the wax and doe 1 or 2 new coats of easy on it.

Perhaps worth start thinking about vacuuming. On the start not necessary to have profi device, vacuum cleaner offers much more better results than hand laminating...

The chemical release agents are the top quality what you can use. There is no need apply others like a PVA or waxes. I'd like recommend don't use anything other if the chemical release agent has been...

on the outside there is hardly any airbubbles. 2 or 3 small pockets between the glas and carbon visible. but. only on the inner lip it lifted from the gelcoat. its a small flange i know. but the...

The air pockets look like bridging which means the carbon lifted from the mould corners. It can be not enough fabric in those corners or the bagging stack and bag itself can cause it. The solution is...
