Just a quick question. I have an ABS Motorsport fibreglass bonnet which I am happy with but it just needs a bit of filler on some of the edges where the flanges are so that it looks a lot smoother.

Now do I just rub the gel coat down so that it is dull and keyed then apply the filler or do I need to do something else ?

Nope, filler will bond mechanically the same, if not better. The issue is fibreglass is often more flexible. You can get gelcoat filler, but it's as tough as gelcoat to flat.

I would use stopper rather than filler for slight skims over an edge, it's softer to flat and will be less likely to crack, key the gell coat and then skim and flat it off until it's how you want.

It's at the back edge of the bonnet that would be up against the scuttle. It's the strongest least flexible part of the bonnet and its most of the back edge. It's more that the join between the two parts is visible I will take a picture when I get home to show what I need to do

I have these two corners to make up on the edge of the bonnet so it looks right.





There is a bit of a small raised ridge along the back of the bonnet I wanted to blend in but it seems like it's equal on across the whole back end so I'm happy enough to leave it

I'd be tempted to try some epoxy on a bit that small, but thick. Cheaper too, for a little tube of araldite.

Back he first question. It is basically the same. But go for some speced as being flexible.

But for those holes. Any will do. But make sure to key the surface and de grease it or it will not bond.

Thank you I will do that then as it only needs a little bit and I have loads of filler already
