Well, after taking the last and all the other posts into account, I have now placed an order with Amazon for the Supertrol in 500ml cans x2 for £17 and free delivery
Had you used my
LINK for supertrol you'd have got 3 cans for £17.07 plus free delivery
or was my supertrol not expensive enough for you
My plan is now that I wire brush / wire wool all the crud off the springs and brake pipes. I will treat with Kurust to eat the awful stuff and then apply Supertrol.
I will follow Doctor Gollum's clear instructions to safely (I hope!! ) remove the sill covers and treat the metal according to how I find it, with Supertrol being applied.
Good plan?
Many thanks all!
Supertrol comes with a straw ,for squirting inside sills ,chassis legs,sunframes ,door bottoms (via the drains if you don't want to take the cards off), wheel arches inside the boot, etc etc
it won't last on brake pipes or springs
springs and shocks/struts, brackets etc you could paint with hammerite or rust protection paint ,along with brake lines if you must.
I use a spray silver zinc galv metal protection paint on brake lines because any failure of the paint will clearly show rust through when next inspected (before MOT) and any leaks of brake fluid would also show better ,its also good to get in nooks and crannies and all round the brake pipes, ferrules,clips (not just the part you can see)
kurust will stabilize the remaining rust once the thick is wire wooled off, but won't protect much , think of it as a primer
I've not used FE123 , but it may be better than kurust (which is more of a DIY product) perhaps applied with a garden sprayer
,which you can't do with kurust ,it blocks the nozzle ,i tried
also worth saying that the factory "underseal" is shyte on the front chassis legs etc and various other areas and if you find rust, cut/scrape the underseal off until you find a good clean surface ,prime and metal paint it then stonechip or underseal
good luck ,hope you don't find any nasties when the sill covers are off , but if you do , at least you can get it sorted and future proofed
My sills where fine ,bar some light rust round the rivet nipples and a few other areas (now treated and painted and squirted supertrol inside), 53 plate with 80K miles (age/mileage has an impact on rust)
