wanna have white rims gotto be hardworking to wash it lor... when u see de rim is dirty wit dust... gotto wash it off... if not, it will eat de pain color... but live wif it... it's normal...
u repaint ur rim, rite... and it oso depends on the paint quality... if de color fades faster than expected... u r not using a good paint...
but once yellow... nothing can be done to it... OR else... got2 repaint it again lor... but this time choose a better white paint... ask the painter... he shud know wat white color can last longer wan... but of course that comes wif a price...
i've been using white car and white rims for all my cars... so sikit sikit know lar... hehe...
