    Fixing Fiber glass around mounting bolt holes.

    Patching up a fiber glass after a lowside @ collie - have the area sanded back and ready to patch with fiber glass kit - one of the mounting bolt holes has been scraped out - whats the best way to reform the fixing hole / is there a product / resin that would work best here for drilling the fixing hole after.

    thanks

    Any photos of the area?

    If not too big of an area try mixing in some fibre dust or microballoons, I think they might be called too, into the resin.

    If you need a small batch of it Ive got some lying around here.

    If not just cut up some matting really fine.

    I just used a washer to get the correct diameter and orientation to lay the fibre and glass over.

    +1 That's how I did repairs on my rear cowl





    Then I drilled the hole out using a doweling bit

    Just adding thickness to the area will suffice for most locations then drilling. I would also highly recommend using biaxial weave fibreglass for damage repairs, I normally use enough layers to get ~400-500 gsm worth of thickness (I've just repaired mine too).

    Fibreglass-resin sales or composites warehouse in oconnor are great for knowledge and products.

    Also grab some peel ply, makes the finished surface much easier to work with.

    More glass fibre, less resin. Resin has no strength and it weighty.
