I should be fitting the bodywork GRP soon, and I'd like a little advice.
I have heard that it is a good idea to paint the rough side of the GRP black, to prevent light passing through it, so making the GRP look better.
Has anyone else heard of this ?
To a degree, it depends how thick the GRP and gel coat has been laid. And also how good the spray job will be. Hold a small panel up to a light, how much light is passing through it. If you can see quite clearly the brush strokes of the gell coat them I'd go with painting the underside.

Thanks, i'll have a check.
I got the last batch of panels before supplier was switched - they wern't terribly good (I did get a discount though). On the holes I have cut the gel does look quite thin.
my new steering wheel arrived today ! looks & feels very cool. Only cost £45 off ebay. pic below.

One thought on painting the inside of GRP panels, it might make future repair or reinforcement a bit more difficult. I imagine that removing paint from the strand side of a panel could be tricky.
I used fireproof rubber paint bought years ago ...Rubbercoat I think it was called . Did the job but as above post makes any repairs more difficult as you'll have to try and remove the coatings .
You can easily remove the paint with a rotery brush if need be.
It doesnt matter if you take a little fibre glass away with it as it will be layed up again when doing the repair.
Personally I would use a thin coat of matt black if you can see through it. Just to give it a slight backing. ;)
Just a thought. ::)
