well if you only wanna buy one of the meguairs bottles i would suggest stage 3 as its a wax.. stage 1 is a paint cleaner so it'll strip any wax you already have on the car and stage 2 is a polish, which is actually quite good, but using these two you would have to seal it with the wax.Would you recomend using Stage 1,2 & 3 meguairs of will just 1 do to start with. Sorry if this all sounds all basic to you guy's just never bothered with cleaning my old car. It was only a Corsa that was bright turquoise! some how just didnt seem worth putting the effort in.
claybars do not remove all wax.........A claybar is literally a bar of clay (not quite as harsh as it sounds!). You use a bit of lube, I use 50% water, 50% car shampoo and then rub it against the paintwork. It removes 99% of blemishes on your car. For instance, my mate reversed into a painted barrel he couldnt see, which left blue paint on his silver car, he could not get it off, I clay barred it, within 2 secs, it was gone! Great for flies etc.
It does remove everything though, so if you have waxed the ares you have clay barred, you will need to wax again. They last for ages too!
