fibre glass repair

[Dipper]

next daft question!

i need to cut out a section of my boot floor due to it being melted by the exhaust. should be a fairly easy repair but ive never worked with fibreglass before. the hole will end up @ 10" square. how do i stop the fibreglass sagging into the hole? screw the fibreglass mat into place first?

You will need to support a patch that size. Ideally you will want to make up a support that has the same contours as the boot floor using MDF or similar =. That or get hold of a boot section larger than the hole from a damaged clam and cover it with cling film. Secure it in place and lay the fibreglass onto that.
I still have the damaged rear clam from my 111R, if you need it I can cut out a section and SE pony express it to you.

Can you post up a picture of the bit of boot floor that is damaged. That way I can get the right bit.

Should be able to match that section for you. Should be far enough away from the damaged part of the clam.

You could get a good finish by making laying up a patch panel off the car on a flat surface, single skin, then secure over the hole underneath with small screws, apply repair and then remove screws. Self supporting repair.

Cheers Mike. ill pm you

ferg, the repair will need to go round the curve at the rear of the boot so its not flat
