lol at do it once do it right...the first time you had sex...did you do it once and do it right,
car modifying is a hobby you will never do it once and it will never be right, even if you went and bought 5000$ wheels and a 10,000$ paint job in a few years you would decide it wasnt right and would do it all again..
So I never beleive the people that say "do it once do it right"The only real factor that matters is how much you are willing to spend to never be satisfied...lol ..
Also did you get the headlight polsih idea from me or was it just coincidence, cause i posted the same thing the other day...you dont even need sandpaper just a good cutting compound on a buffer..
