brackets on do not want to glass them in.

What's bracket going to hold?
Tiger Seal/PU adhesive should do it.

They are holding the top of the inner wheel arches 3mm thick plastic.
Thet where attached with tiger seal but thiy have just fallen off. They do have a seal on them which means when the bonnet is opened the seal puts a
bit of pressure of this bracket.

Re brackets
Hi I've used panel bonder from cbs.....clamp in place for 24 hrs and then use 3 or 4 layers of glass matting over the mounting point, I"ve
used that method may time and not had any problems.......

I used a two pack adhesive for attaching car body kits, worked well on aluminium brackets. I drilled several small holes in the bracket to let the
adhesive ooze through and cleaned the area before fixing. Very strong bond.

I used No More Nails to hold a few non-structural items on to the inside of the GRP, like grilles inside the bonnet vents. It sticks incredibly well.
Just make sure you use the waterproof variant if anywhere near water (obviously).

Overlaminating is the most secure method. It will also depend on what the brackets are made of. Alu brackets need keying up, but the Ali will oxidise
over time, reducing the effectiveness of the adhesive bond. I have a variety of brackets bonded onto gfrp parts, and always drill the brackets to
allow the adhesive to come right through. To be bomb proof, a couple of layers of glass on top would be ideal.
