With the mould now ready I waxed and polished it and again sprayed a layer of PVA release into the mould. The PVA release agent does work very well but it leaves an inperfect surface as opposed to just wax which leaves a beautiful polished surface, because of this I painted 2 layers of white gel coat into the mould in order to easily sand out any minor surface inperfections.
When the gel coat is applied it falls into the hairline crack of the 2 part mould, this shows as a proud line on the moulded part which cuts away very easily with sand paper.
I made carboard templates of the matting sections needed to make the part, I then tore the matting useing the template, this method ensures that all the matting sections will fuse easily facilitating in easyer/quicker lamination.
As the gel coat became green/tacky I sprinkled 6mm choppies into difficult places then proceeded to lay 5 layers of matt, 3 x 350gram as it moulds easily and 2 layers 0f 500gram matt to add strength.
Whilst the fibre glass was green I trimmed it to the bottom flange with a knife, the part is now finished and will require minimal tidying.
