Floor pan rust removal and finishing

Billy Smalls · Jun 12th, 2017, 16:48

Hi

I am in the process of sorted my 144’s floor pans. As is so often the case, rust is the result of a leaking windscreen (yes, the stupid clips) keeping the woolie matting under the rubber flooring soaked, with nowhere for the water to go.

Three of the four circular factory holes, that had expanded with rot, were cut right back and plated over to a good standard about 2 years ago.

Windscreen is now sealed (welding job pending) so I have taken out the rubber flooring, woolie matting and the passenger front seat. I have also prised off all the sound deadening (which traps water in the small grooves that run along the floor) I should point out, I have to use my car every day and I have to work in the road with no power supply.

The floor as it stands is actually very good; I’ve gone over it with a fine toothcomb and its all truly surface rust except for 2 pin holes no more than 1mm diameter (measured back to bare steel)

My question is options from here on. Ideally the car would be off the road and being shot-blasted or similar but needs and budget limit me. The options I’m thinking are:-

1. Paint strip the entire tub, re-seem seal with Tigerseal, Bilt Hamber Deox Gel, Zinc prime and top coat of flexible product. Not fussy about colour.

2. Sand back the rusty bits only and use Bilt Hamber Hydrate 80 where I need to. Zinc prime and top coat

There are so many products out there; I can’t afford POR15 and have learnt the hard way with Hammer****e (good for gates & railings only IMHO) but either way don’t want to be doing the job again in 5 years time.

Does Nitromors (or similar) wipe out seam sealer?

I can’t use power tools and frankly they create so much mess, I try to avoid them.

Like I said, I know the correct way is to strip the car and acid dip / shot blast but can’t do that right now, as much as I’d love to….

Any tips? Cheers all
