Cavity wax

denisob

Dear All,
I'm looking for some feedback/info on cavity waxs. The sills in my mini are rusty and I want to stop the rust spreading and protect whats there.
Whats the best product to use???
Waxoyl and Bilt Hambler claim to be kill existing corrosion. Do they do this??

Thanks
Denis

the only solution to the problem of rusty sills is to have them cut out and repaired with fresh metal, then have the good metal treated and protected to keep it good.

If that's not an option right now and you just want to prevent them getting any worse until you can get around to it, I suggest wire brushing away the worst of the rusty/flaky stuff then painting them inside and out (as much as possible) with POR15 and then injecting in Waxoyl wherever possible. Then save up to have them repaired properly, as above

Never heard of that being done before, is this a new practice, and why do you not recomend it?

Because it weighs loads and as the sills are then full of resin any welding work after would be impossible.
Plus the car looked like it was filled to the hilt if you went around tapping the sills!!:D

Yeah, and I can imagine any moisture that's there is trapped for good.(and in this weather there IS a lot of moisture)

The continually best product in long term tests in German classic cars is this stuff:

It is a bit awkward to apply though, as it has to be heated to become sprayable
