Boot Floor Fibreglass Repairs & Pop Rivets
Posted: Tue Apr 22, 2008 2:25 pm
Can anyone offer any tips on repair of horizontal fibreglass sections.
The rear of the boot floor was previously badly repaired using aluminium pop rivets, some ally sheet and a sandwich of fibreglass both sides. There was inadequate prep with some of the fibreglass applied over paint. In addition the steel mandrel (pop piece left behind in the expanded aluminium head) had rusted & spalled, forcing apart the already bad repair.
I now have removed all the above and sanded back to original glass. There are some rather large holes and missing sections. This is above the rear mount for the silencer.
My first plea is to all repairers is not to use pop rivets if they are to be permanent and incapsulated within the fibreglass. If they must be used, then at least consider all stainless or aluminium types.
Secondly, are there any recommendations as to how to form a temporary mould on the underside. This would have to support the new glass repairs.
Regards
Gerry
