hi guys! got a pretty good question here. I have a set of staggered amg rims and they are silver with clear coat. but you know how they clear coated to whole rims including the lip. how can I take the top coat on the lip with out touching the clear coat on the silver painted parts. the reason for this is one of the rims clear coat on the lip chiped off and I noticed that it was like polished and was thinking if I can just remove the clear coat on all the lips will give a nicers chrome finish to it. :thumbsup:
Some wheels are clear coated to keep the magnesium from oxidizing . Bare Mag. will turn gray quickly with any moisture or rain / road acid . A silver anodize may hold up better . If its chromed steel is rare to find the coated.
You could test an area on the back side of the rim , use a bathroom rust / mineral remover on a clean spot . If it turns dull quickly or foams its very high in the percentage of magnesium , If its unchanged its more aluminum and holds up better to corrosion .
Some spray can clear urethane will hold you over for touch up . Depending how picky you are you could chemically strip / pick / wet sand off the old edges before painting . Depending how hard the old coating is, it could be a job to remove it . Some big wheel detail shops will strip them bare and re-coat them in two part catalyzed clear paint ( not cheap ).
