Recommendations for Rust Removal Products?

Now that i've found the product I was going to mention, i'll post my 2p worth....

Buy yourself a cup brush set for your power drill, use this to remove the rust, the paint and any contamination on BOTH sides of the affected area.

Clean the area with alcohol (IPA will do).

Dry and heat the area with a hair drier or very carefully with a hot air gun.It needs to be warmer than the ambient temperarture to stop moisture condensing on the surface when painting.

Then use "Bilt Hamber Hydrate 80" on both sides to kill of any microscopic bits of rust remaining and seal the area.

Then use a primer and finally the correct colour paint for the car (spray).

...and that's the problem on a multi-skinned area like this.

Thanks so much for all the advice, I'll go through the posts again shortly and will try to get photos next time I see the vehicle.

I've been back to bare (shiny) metal before and used Kurust before primer. The rust returned within a couple of years but the repair looked ok, it meant no sharp edges that might fail an MOT.

The dinitrol product sounds interesting, I have a tin of Waxoyl (clear coat) lying around but doubt it's a suitable substitute.

Bilt Hamber hydrate 80 looks like a good product with a similar reputation, may end up ordering some of that to give it a go. I like the sound of white vinegar too. :cool:

Epoxy primer has been mentioned. I have a "rust protection" primer spray can and the colour is red-brown. I previously used Hammerite rust primer tin (grey colour, applied with a brush) which frankly seemed useless as the rust came through very quickly. I've got black paint which I used as a guide coat last time, so it's good to know I was doing something right.

At best, without replacing the arch, you're going to slow down the process for a while, and a decent repair might at least allow the family member to trade the car out for something else.

Being realistic about it, I think this is what the owner considers is the best way forward now. MOT due in Jan (so it gets done exactly one month early) so if it manages to pass, it'll be worth a bit more with a year's MOT.
