Here is the painstaking process he had to go through in detail to achieve a painted rim...
Dave started by meticulously flattening the wheels, barrel and spokes with 1500 grit superfine wet and dry which took around half an hour per wheel.

|Inside of the wheel barrel masked|
|Masking around where the spokes meet the rim was apparently fiddly|
|Spokes being masked|
|All spokes and wheel centre masked|
|Wheel barrel masked to avoid orange overspray|
|Wheel rim sprayed with RAL 2004|
|Two wheels painted with orange rims|
The wheel was then completely degreased and the ridge between the orange rim and the black of the barrel was again flattened with 1500grit wet and dry to make it look as seamless as possible.
And finally a coat of clear coat was applied, left to flash off for half an hour or so, then another clear coat applied to give that high gloss finish.
|Wheel finished off with a couple of clear coats|
|Masking removed and I think they look superb|
|Wheel with orange rim test fitted|
To cut a long story short - it didn't happen. Why? The sidewall of the ZZR is so stiff that it was practically impossible for the fitters to get the tyres on without damaging the orange rim. Nightmare!
So after weighing up my options and speaking to Dave I'm going to find an alternate tyre fitter, and somehow try to get the tyre sidewalls slightly warmed before getting them fitted. After asking some advice on blatchat, it seems most people don't experience a problem fitting ZZR's; but then aren't so 'precious' about damaging the rims.
Anyway... Dave said get them fitted, see what damage (if any) is done, and then he'll sort them out and make them look perfect. He's really done a spot on job and comes highly recommended - a link to his site is here http://www.daytonacoachworx.co.uk
I see now why no-one else has painted rims on a Caterham and it also makes sense why the new Apollo wheels on the 620R have diamond cut rims too.
