hi all, i am just sorting out my porsche split rims. ive removed the centres and basically want to get the colour changed, A guy at work said he paid them for me for free if I buy the colour I want. he said I have to remove the old paint, so started using paint stripper, but its leaving behind little bits of paint. So was thinking might be quicker to get them acid dipped, so the question is does anyone know of somewhere cheap that would do it? round hemel/watford area,
