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
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.

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
