I thought I'd give this a DIY thread as I'm so impressed with the results! I will never get a diamond cut wheel refurbed again.

I used Halfords emery paper kit, first the medium grade and then the fine, always going in the same direction, until you can't see the damage anymore (if there's some really deep nicks then you might just have to reduce their visual appearance).

You then want to rub down the repaired area and a couple of inches around it with 800 grit wet & dry so you can blend the new lacquer in with the old. Clean thoroughly with 70% IPA before spray lacquering with alloy wheel lacquer, I used the E Tech one on Amazon.

First do a light 'tack' coat, then build up around 3 more coats every 15 minutes then leave for at least 24-48 hours to fully dry before wet sanding with 2000 then 3000 grit and finally buff to a shine with Meguiars Ultimate Compound. Leave at least a week before sealing, so all the gases can escape.

Temperature is also important, you want the wheel and spray can to be at least 20°C throughout the spraying and at least a couple of hours into the drying process.

If you look closely you can see where the repaired area is a slightly different colour, but you would have to be looking for it.

Before and after:

Good job! Did you take the wheel and tyre off for the repair?

I did something similar recently with very fine wet & dry (wheel and tyre still on) to remove a small nick but I haven't polished it or lacquered it which has left a flat spot. It looks much better than before but dosen't look as good as your repair.

I think I'll have another go when the weather gets a little better.

Winter wheels are on at the moment so did this in my garage with no rush to get it finished, just masked the tyre.

Was the wheel lacquer the spray can type? Did you lacquer the whole wheel or just the smoothed/polished section? Keen to give this a go on my summers while they're off the car

Yes this one: https://www.amazon.co.uk/Clear-E-TEC...ch+alloy+wheel

Just lacquered the repaired area, but obviously it overlapped on to the unrepaired areas.

Before and after:



might be a silly question but should the tyre outter wall take damage first before alloy get grinded? your tyre looks intact where alloy is damaged

Good job Tim, but not sure you'd get the same results with a deeper scuff?

Still saved you some money and you've shared another good fix post

I forgot to mention cleaning with IPA (isopropyl alcohol not India Pale Ale ) before lacquering, first post amended.

I've done a couple of my own repairs on machine polished wheels. The problem has never been the finish. but finding a decent clear coat that's hard enough. When I've had them done in the past by smart repair outfits. They always add Rocket hardener to the clear coat.The normal stuff available from motor stores ain't up to much.

This E-Tech stuff has very good reviews, so hopefully it will be up to the job.

That's a pretty decent job there dude.

I'll bring one of my tyres round for you to do your magic on

Ps before any smart Alec says it should be rim and not tyre - just think about it
