Ive got my fuel tank out at the moment to replace my P bracket bolts.

The tank is 12 years old, powder coated aluminium. It's showing signs of crevice corrosion due to the fact that strips of self adhesive foam were stuck to the stringers for the tank to sit on.

Apparently the way to do it is to sikaflex some sort of plastic strip to the underside of the tank where the stringers are but I'm struggling a bit to find suppliers. Also I'm not sure what type of plastic to use. Some can't be bonded, some may have carbon content etc.

Ideally strips of 40-50mm x 5/6mm x maybe a metre long.

Anyone here involved with the plastics industry?
 
Thanks, nylon sounded like a good choice but I read it can retain 7% of its own weight of water. Not sure if that may lead to further corrosion.
 
Various people sell plastics on ebay.
Motorcycle practice would suggest sticking on a solid rubber to avoid point loading the metal and avoid trapping water against it.
I'd look for solid neoprene or similar and a pot of contact adhesive, probably after re-coating the tank bottom with epoxy.

Depending on what you want to use as an adhesive, I think epoxy will stick to ABS PVC and polycarbonate. Maybe others.


Tip: if you want to glass PVC you should heat it very rapidly till you see small black spots form on the surface, this is burnt plastic.

It helps to provide a mechanical bond, blow lamp or small gas bottle with burner tip fitted is best.

I discovered this when doing a test to destruction, something I often do sadly, but it proves the point and I hop reduces failures.

Good luck and fair winds.

The alternative is to have joints that bulge (2 pipes the same size with a larger pipe covering the two ends) using a good quality PVC glue and wrapping the whole joint past the outer joint with enough material to prevent any movement using the wedge effect.

Good luck and fair winds. :)
