Hi Guys,

What is the collective opinion on how to repaint/preserve the underside? I've removed most of the previously applied underseal (it's only taken about 3 weeks, and is possibly one of the worst things I've ever undertaken) and now want to repaint the floor.

Should I treat the rust with something like Kurust, repaint using red oxide primer or use Hammerite Straight to Rust paint on the bare floor?

I can remove the "loose" rust with a wire brush on either the angle grinder or electric drill, but cannot get back to bare metal.

What do you think?

Regards

John

I used what I had in my shed and gave my saloon 2 coats of hammerite and 2 coats of waxoyl letting it all dry in between coats. Try to get the car as high as you can on stands/ramps and get into all the little parts on the xmember and above the axle as well as the petrol tank and under the wheel arches. It's a pain to do but worth it in the long term.

I used a product called bondarust then the red oxide then a black topcoat (bottomcoat?). I don't rate hammerite much but I find most one coat paints a bit useless.

It will eventually get waxoil but its not on the road yet.

When repairing my Moggy I got the whole car on its side and stripped everywhere back to bare metal. It then had 2 coats of Zinc rich primer and rust converter in the relevant areas, 2 coats of chassis black then a final couple of top coats of waxoyl....................if it rusts now ill eat my own face!
This is of course, the extreme way of protecting the underside. BUT, well worth it. If you cant get the car on its side then I suggest you get it well up the air, clean away as much crud as possible and either use zinc rich ideally or red oxide primer followed by a decent tough topcoat of some description. Should do the trick
