    If its only cracks in the gel coat then a Dremel with one of the glass (window) etch balls will grind the cracks out down to the glass matt very quickly and easily.
    I then used polyester 'flowcoat' (gelcoat) to fill the cracks back in again and then flatted back.
    For pinholes you can use the dremel and flowcoat (or filler) to get flat.
    Then use Epoxy primer to overcoat as not many primers stick to glass that well.

    Yep cracks need a hole drilled at the end but they still will need grinding back to eliminate them. I always grind back to glass and then refill with glass and finally skim with body filler.

    I was told to always drill a about 4mm hole at the end of the crack. This will stop it spreading.

    Neil 2 pack primer won't fill the pinholes properley as it will sink back, Get yourself some 2 pack stopper which 9is like creamy body filler.

    Yea Neil ,use a polyester (fine) filler prior to priming,for pinholes,and i really would recommend,you take a couple of hours extra at tis point,even if it means putting "another"spread of filler in,the effort is worth it in the long term,once the paints on thats it dude ,Bry

    re fibre glass prep

    hey thanks boss , is it neccesary to fill up pin holes etc then prime with 2k as this does have substantial filling properties as your most probably aware of..as this mould is pretty pitted etc. its not gunna be a showjob ,just a clean tidy attempt
