the person who I bought the car from showed this product to me for removing the stains on that wheel, it was actually working rather quickly. But I rather have the confidence of BITOG recommendations on what will work best, as I don't mind buying the right products but I don't want to use less effective products and waste time & money. I only intend to this once as I'm not into making my car "shine" but I rather don't want it to look oldish. Another recommendation I'm looking for is Rain X Glass Treatment I have a few friends that use this and say it works, is it really that effective? just follow the procedure on the back of the bottle or you guys have additional steps I should do? also how often should something like this be applied? last but not least, I use the turtle headlight restoration kit to clean up the yellow on our headlights, I get em fairly clean but not like how some of you guys get them to be almost new looking, if I decided "buffer" is the way to go then which one would I buy for this purpose and how much? we have some air buffing tools at the family shop but I have no idea which pads to get from where that fit. The yellowing returns fairly quickly as to make my efforts useless, I was recommended this Optimum Opti-Lens Permanent Headlight Coating how effective is that? it's a little steep for the cost, I mean how many applications and how long will it last? I can get replacement headlights for a little more and would be new... Headlight Lens Sealer here is another product as well, any info will be greatly appreciated.
