best stuff to use for rustproofing on sills etc

[matt86]

What's the best stuff to use to rustproof a car, i used kurust on any surface rust patches which were very minimal, then sprayed waxoyl on from halfords, which also has a rust prevention/eater agent in. Would terraseal be better?
i still have one sill to do and was thinking of doing where the arches sit under the mtech kit, for rust prevention in the future.

any recommendations on cleaning underbody of car and rust proofing etc?

If there is any signs of rust on the cills, clean them back to bare metal , then paint with stonechip paint. That waxoil stuff with the rust killer in it wont get rid of the rust and it will come back underneath.

you ask a few times about this sort of thing, it sounds like you need to do a proper job- car on stands/ramp, wheels and arch liners etc removed and strip it all back, sort rust properly, re seal it all properly, if you do little spots here and there and mess about- your forever chasing it, and if you just touch up a bit thats got deeper lurking and waxoyl the top as abovbe- it will fester away

also- did you paint it ? kurust isnt great, the magical fertan is much better, and get some touch up paint from paints4u (£12 odd) which somes perfect color match, and when you do any little bits, you paint it after if its just touch ups, then also if its a visible area, you can then blend with a g3 type product after

youd do better to post pics and close ups of the areas you are on about
