Repairs to fibreglass caravan (A bit OT )

We have a 1950s portafold caravan which needs a structural hinge repair in fibre glass. I have tried using Davids which had the strength of cardboard. I would like to know if there is anyone within say 50 miles of london who could do a real strong job for me Cheers Phil

In general to repair fiberglass you need to totally remove the crushed and split areas, then simply feaher edges off, and start re-laying new chopped strand nat and resin - this is all available from e.g. HOLTS.
You may need to use lots in layers to build up to e.g. 1/4" or more.
If you need to support the repair, use e.g. balled up newspapers or aluminium mesh on the back side. Mesh is a bit better for large areas and can be screwed - or even taped - in place.
Once you have the strength back, you can prettify the repair with car body filler - P38 or its it P40? and sand it all to a decent appearance.
Car spray paints will finish teh job.

Isopon fibreglass mat and resin is much the same as any other for this sort of application. The strength depends on the number of layers and thickness. Of course it could be that the hinge should have a re-enforcing plate to spread the load.

IIRC repairing fiberglass is best done with epoxy resin instead of polyester resin.
Ask on rec.boats.building for the definitive answer and have a look on the web for west systems epoxy, they have a wide range of starter kits, mat, cloth and fillers.
Or look for a small boat repairer that specialises in fibreglass repairs.
cheers, Pete.
