+x+xAs you can see there are different colours on the cured mould surface. Probably I failed with lamination and got some air under the last layer...any idea?
What tool & resin did you use to wet it out? Any heat applied in the process? What type of fiberglass mat was used? What ambient temperature did it cure at?
Does it really matter if the other side is clean?
Just like Uni-Mould system. Vinyl gelcoat, 2x100g CSM coupling coat with vinyl resin after that 4x450 CSM with polyester tooling resin. Ambient temp was arround 17-20 Celsius. I used brush to apply the reinforcements. Non of any heat applied...
What you mean exactly on the other side?
