ok first of all i wanna make sure you all know that i am not advertising for this company. i simply wanna help you all out. I found this small polish company that makes a great product. the company is call ultra finish. its amazing. i found some old man selling this tuff at a swap meet and decided to try it. i had water spots on my car and could not stand them. i also had dirt under wat was probably twenty layers of wax build up. I put this tuff on my orbital buffer from sears ha and everything came out. it took it down to paint and polished it up so nice i almost cried. haha.(i like my car alot)afterthat i used some basic NU finsh wax and it was done. if i had not used this tuff i would have painted my car. now i can wait another 5 years or so. look it up online. im telling you, its crazy
