I've got my rusty sills off my car and am pleasantly surprised that the under sills are very good on the sides of the car but underneath, especially near the jacking points where the underbody protection has been rubbed off it looks like deep rust. I've tentatively brushed and poked these areas and they're still quite solid so no need for any welding.

A number of years ago I used Hammerite Kurust? or similar sounding name which was a brush on product that stabilized rust into a surface ready for painting/filling.

Any recommendations for a similar product?
 
I’ve been really impressed with Bilt Hamber Hydrate 80 rust converter. Expensive but a little bit goes a long way.
For rust prevention once you’ve finished ( or even directly over light surface rust) then Lanogard has proved very good and effective. Again expensive but a little bit goes a long way. V easy to apply, and in my opinion it’s such a thin liquid it seeps into seams, nooks & crannies much better than Waxoyl, which I always had to dilute with white spirit.
 
Vactan is a good product which converts the rust into a stable, paintable surface.
Have a look on eBay Garry. Apparently the Dutch sailing barges use it below the waterline on steel hulls. Disney and Universal Studios also use it in their theme parks too.

Forch Korroplex is a really good one, but I don’t know how about the availability in UK.

+1 from me. I've used Bilthamber Hydrate, Deox and Ge-Ox.

Also- Aquasteel rust converter does a good job on surface rusting. It leaves a good surface for paint.

Bilt Hamber Deox gel is amazing if you want to dissolve rust away, as opposed to converting it. Takes more time and effort though, but will get you back to clean metal for painting etc.

Gratuitous photo of jacking point after cleaning with BH Deox Gel. It was really crusty and pitted to start with.

A few have used por15 and found rust forming underneath so caution with this product???
 
After reading Dr Wong write up on his sill refurb before I started my project I went with BH Deox Gel for killing the rust. See results from pics below. Must admit I was a bit worried when I saw the inner sill surface on first look see in pic #1.
