The real challenge is to make good 'kerbing' damage with the tyres on! Much easier with just the rims to contend with, rubber off!
: Personally use a home made, scraper first, made from an old industrial hacksaw blade, edge ground to a right angle, to level off the rough protruding spikes of alloy before applying a filler. PP is the one I go for, as it's the easiest to sand. Use 180, then 320 Aluminium oxide to flat back, dry, not wet.
Then prime with filler/primer/ undercoat, then 'nib off' with 500, before applying the silver, locally with a Badger. Then lacquer, leave a couple of days, compound with Farcla medium, then 'T' cut burnishing, then wax. The trick is blending the 'Boots' No 17, metalflake nailvarnish into the surrounding original finish. Not easy.
