I use the one that Lidl sell, which is basically Krust , on the lawnmowers. Works really quickly and is easy to paint over.
Just don't tip any unused stuff back in the bottle because it renders it useless then. Small bottle lasts ages.
Same sort of stuff in Wilkinson's at the moment for less than a fiver.
I've used that kurust stuff years ago on the bottom of a door, didn't work well, probably down to the fact the corrosion was coming from the inside out.you mean that hamerite kurust, ya only get a little bottle of the stuff.
