I borrowed a grinder and bought a wire brush and went at some rust on the floor of the kombi yesterday, the plan being remove rust... fishoil... paint... underlay... carpet. Unfortunatley some small holes were reveild :o. See pics.

I'm not expecting to get to "as new" show winning condition with this I just want the kombi to last, so what do I need to do?

Buy panels, cut out lump of floor weld panel in?
Weld a flat panel over the top?
Fill the holes with something?

BTW, I've done a little bit of MIG before but not for a few years and I dont have the equipment myself.

All advice welcome, thanks for reading.nn[ Edited on 31-7-2005 by kombipom ]

very small holes.. could u braze them up?

If the floor is still really solid and you can guarantee no more water leaking in. There must have been water getting in somewhere to cause this.

You need to clean all of the underneath area to bare metal as well. Then you have several options. The best from the top down.

Cut that section of floor out of another bus and weld it into yours

Weld up each individual hole and grind it back

Put tape under each individual hole (once underneath is all bare metal) Then put fibreglass resin in each hole. Seal entire area underneath and inside with a fully sealing paint like Killrust. Or even better POR15

Thanks for the replies guys. The water was coming in from a sunroof above that area, the rest of the floor is totally fine. It doesn't seem to leak now but obviously it was sat with wet carpet for ages.

I'm planning on cleaning, treating and painting the underside anyway, will the resin hold up for a long time or is that pretty much a botch that I will have to sort out at some later date anyway?

If you treat it and fully seal it inside and out, it will last a pretty long time. You will have to seal it inside and out before going out in the wet.

Thanks, she's not going anywhere for the moment, so I'll get some resin tomorrow and get on with it.
