Mornin all!

Anyone know anyone who can do repairs on alloy rims with minor rim scrapes such as those created when becoming intimate with concrete gutters? And If so, do you know what they charge?

I recently bought an R33 GTR and the wheels it had in the showroom were nasty 3 spoke uglies. I asked them to replace them with the original GTR rims but the only ones they could get were slightly scraped.

Any help would be appreciated as these little things are as annoying as flies up your nose! Well that's just me.

Thanks

O.K, I've repaired gutter rash before on rims....I get really cheap rims by buying them all scratched up!

Depending on how deep your scratches are, this process will work. I have used it on scratches up to 2mm deep. Anything deeper, and you'll probably need to have material welded in so you can rework it.

Remove tyres from rims(makes things a LOT easier).

Start sanding with a sanding block and very coarse wet/dry paper, I usually start with 60/80 grit. Work the paper so you follow the rim around, be patient, the early stages with the very coarse paper are when you remove lots of metal. You'll go from 60 grit to 180, then 240, then 600 then 1200.

Keep going to a finer paper(I like to do all the rims with one grade, switch grades, go over them again etc, just so you don't get confused)

You'll need a half sheet of paper of each grade per wheel, maybe a whole sheet of the coarser papers if your wheels are a bit mangled.

When you get to the 1200 paper, you have the choice of leaving it in the 1200 paper look, which is a nice brished look, or polishing. I use that polish in the pink tube, forget the name at the moment.

Allow 2 hours per rim and you should get close.

You may want to consider stripping the old paint before you start this if you have any old paint on your rims, any god stripper that's safe on aluminium will work, paint comes off aluminium easily.

Regards, Andrew.

      This could be sold and shipped to the US for many gold pieces. RMS has no say in that. Ask various Western Sydney inhabitants how it works.

      Ha ha ha, mine loves to spend, all on the dogs (they're our kids, and her spending would likely rival that of some people raising children!) the only benefit is, her spending is tax deductible as she runs a business in the dog industry 😛 The above all means she can spend race car budget quicker than I can. 😛 That and a lot of the things I want are very expensive, and I can be a bit "you want how much for that?!" And at other times overly impulsive. Or I start the w days of research, get to day 1.5 and get really annoyed that no one will advertise actual specifics and it's just marketting BS and I go "well, now I don't want anything to do with that now!" Also I hate paying lots of money for something I can make from $50 in materials. Then I get the shits halfway through making things and wonder why others who just buy parts have more fun... 😛

      Their 240Z with the RB26 would be a real nice thing to have in a garage to come out for an occasional weekend cruise It's such a cool thing in so many ways Sadly, we have a blue 240Z shell that I walk past every day, just sitting outside a shed at work, it has been slowly disintegrating and falling apart into the ground for the last few years, the owner cannot be found, and I am unable to "claim it" I've been told by work and the RMS, the rust in the body is excessive though, and it has had most of the salvageable stuff, like panels, trim and switch gear stripped off it over the last year or two, work keeps threatening to put it in one of our metal scrap bins, I wish they did though, as it makes Mark sad walking past it

      Good tips, I like it! 😂😂 My wife is a LOT more frugal than me so it's only me we need to worry about! A splurge to her is buying 2 pairs of socks in one visit at Kmart!

      Haha, the appropriate response to the question "Is this new?" is "I've had this for a while.". With the unspoken small print that a while may be the time since this morning or five years ago   And to be fair I learned that from the best, i.e. my wife. Because it goes both ways.
