My venerable vehicle has alloy wheels which have been powder coated,
Redone in about 2008.
A couple or three (maybe 4) years back two of them started failing - air leaking under the coating giving a poor seal to the tyres.
Took them to a local wheel fettler, and amidst much sucking of teeth and "shouldn't fail like that" they re-coated them. Said the previous firm hadn't cleaned the wheels up properly before re-coating them. Acid etch I think.
Anyway, subject to checking with a tyre company, I think I have the same problem - two wheels with a slow leak..
Looking at the state of the wheels (the coating is wearing off 3 of the 4) I reckon that it is one of the new ones plus the third of four old ones which are failing.
So - any idea how long a coating should last, and any recommendations for a national chain (perhaps) who are reliable?
Don't know if the local firm are as good as any other. All I have to go on is the suspicion that of the original 4 one is still good, one is failing, and they are a lot older than the two newer ones, one of which is good and the other failing.
I am judging the age of the wheel treatment by how much has work off.
Also considering looking at scrap alloy wheels of the same size, new alloy wheels of the same size, or even steel wheels.
I would prefer alloy wheels as the car (although old) still looks reasonable. However the cost of a new set of wheels is likely to be more than the resale value of the car. (Then again, so is the cost of 4 tyres and a tank full of petrol).
