I'd put the time and effort into waxing/claying mine, but the sheer number of stonechips et al on the bonnet and front bar kinda make it redundant. Wash and maybe a light polish is all I can be bothered doing most of the time, and haven't done either in a loooooooooong time (evident by the fact that my wheels are just about black from brake dust) What year model is your Corolla? The paintwork on my 1995 Corolla has oxidation, which sucks. I also think the boot has been resprayed by the previous owner, cos when you look at the boot then the rear side, the boot is heaps clear & shiny, & the side is dull and cloudy. Bit hard to explain haha. i think i know what you mean. my cars a 96. But as for paintwork i got a simular deal as well. The car is shiny but the front and rear bumper looks like a different paint colour.....i think you'll find its because the bumpers are plastic and not metal like the rest of the car. I take it paint gives different affects on different surfaces and materials.
