Fibreglass advice

[caduceus]

Whilst attempting to put in the clear front indicators on the Cerb, I broke off a thin piece of fibreglass from the round mould that houses them.



I've pretty much zero experience in fibreglass repair, especially this thin and contoured.

Any tips on how I should tackle this and what products to use would be greatly appreciated.

Thanks

I would use some Isopon P40. It's a fibreglass repair paste that sets very hard. Daub some of that on the back of the surviving GRB around the damage and press a piece of mesh into it to act as a skeleton for the missing piece. When that's gone off, trim the mesh to shape with scissors and use a small amount of P40 on the front of the mesh and where the mesh meets the GRP. Don't use too much because it is very difficult to sand down. Finish with body filler (eg P38) and primer filler, hone to shape and paint.

Personally I wouldn't be undully worried. The lamps are sikaflexed in anyway. When you hold the new lamps in can you actually see the damage? Also a thin bead of silicone is always used around the lens on the outside and this will also disguise and cover it.

Err, yeah Its quite a hole.

Farmyard, I hear what you're saying. I might give it a try with some fibre matt. But it being in a conspicuous place, I don't want to fk it up
It will be going in for a full body respray some time next year, so I could even leave it till then and fill it with some clear silicone

It is isn't it! Sorry. I didn't see the top foto - I was just looking at the bottom one, it doesn't look too bad in that one.

On second thoughts, my idea is crap because you won't be able to get the light in flush afterwards. How about refit the light with loads of Goo(tm) and then just patch up the gap with a bit of filler?

Goo?

I think a bit of surgery is in order this weekend, with some fibre glass matt and resin. Then filler that I can rub down. Thats the car, not me

I'll post the results after
