Before you go there WARNING,if you love your car the material on this site may cause you to spend money on car care products,spend endless hours detailing and ultimmately make you store your car for the bad weater.At least that's what it did to me. http://www.autopia-carcare.com/
I used to read at the autopia site. Until they made you log in just for read only. I personally don't go to any sites where I have to login just to browse around. I did find it to be a good site for learning things about paint care and detailing however.
If I need some tips or info etc., I go to this site now:
