Default Fibre glassing question..Fabby ??

Hi.
Im about to modify my Triton scuttle. (Widen it)
I have made up the "Splash" molding as Mark sudgested.
Question is,
Do I need to use Gelcoat before the matting or will just the resin be OK?
I intend to spray it anyway so finish is not an issue.
I have some very old gelcoat in my garage.(25 years )
Does it go off?
Sorry if these are dumb questions, but what I know about fibreglassing could be put on a postage stamp, and still have room for the queens head....

Yes mate it goes off, resin and gel coat have a shelf life of a year i think it is if stored in right conditions.
You might be ok just using matt and resin as no doubt it will need a skim of filler to get the levels right as not dead flat on the top...

Cut the matt to fit into gap, nice sharp edge for first layer then 2 over the top overlaping by 4 " or so either side...dont get it too wet and not too dry

Yeah something like that but you will know when you do it, have a look on the underside(if i did it right that is... ) how it looks and aim for that finish..although it's cured it kinda looks wet/shiney well ish..Too much resin and it will get hot and be brittle not enough and it will fall apart.

just by coincidence ive been doing exactly that to a westfield scuttle that i picked up before i knew it wouldnt fit and a nose cone that dont fit either
both bought before i started my chassis and before i came here and learnt my mistake
if it works itll be good if not its only time and a little bit of resin etc

OOPS! did you wax the panel before you applied that?
or is it delaminated through not being enough resin or did the resin go off before you applied it?

I would say you never waxed it. It sticks like shit to a blanket when you don't want it to but when you do it will fall off unless you prepare the surface...good fun aint it

If taking a splash mould then wax 3 or 4 times and pva if not sure on the surface.

If repairing then badger the surface with gritty paper to key it then wipe with acetone to remove the wax present in resin/gel coat.
