Hi i use some blingin gold holographic rim tape on my front hog rim and some holographic chrome rim tape on my rear gold koxx rim.
I got 4 rolls for £2.50 off ebay, green,gold,silver and blue. Its basically for craft use for cards etc. But works great as you just stick it to the rim tape you have already and it works a treat B) .
Cheers Peter
