Alloy tart up...

[Upatdawn]

Is it much trouble to tidy up this sort of laquer mess?

all 4 of mine have some

[Refined Detail]

Just get them properly refurbed, ie shot blasted or acid dipped back to bare metal, then powdercoated or wet sprayed.

[paintman]

It isn't a lacquer mess. Following damage to the paint, water has penetrated under the paint & is corroding the alloy - hence the spidery lines showing its progress & the areas lifting.
Best dealt with by tyre off, strip, repaint.

There is a Pistonheader called 'Budaholic' who is an alloy wheel refurb chap. Does good work by all accounts.
I think it's called Xpress alloys..?
