I have used Isopon P40 to fix my GRP cycle wings onto their metal brackets. Does anyone thing this won't be substancial?
It will be easy to stick a layer of chopped strand matt over the top just to be sure, but is it worth it?
Cheers,

Yes the P40 is polyester based and a crap bonding agent, bolt or laminate them in as u suggested, a word of caution though, adding CSM is a secondary bond and not as strong as the inital layup.
Shug.

Worth having a look at this recent thread on the same subject,

Looked at a Caterham at Autosport last weekend, bonded, nice neat job; no screw holes to to split or craze.

Cheers guys.
Decided to smooth down the rough p40 and then put a couple of layers of CSM over just to make sure.
Watch this space as they say and if your behind me on the way to a show, duck if you see a red GRP cycle wing flying towards you.
