Sanded mine too, but i did not realize i had 400grit, when i was buying the sand papers i only looked at the price with the grit and took the paper next to the label assuming it was the corresponding one... little did i know the grits are written in the back which i thought were random numbers.
Anyway, i had 400, 800, 2000... >Fail, it turned out good but i wasnt satisfied, maybe coz J picked up that i had 400 and no 1200.. so did it again, this time, with 1200 then 2000, mother's liquid metal polish.. cant say its like brand new, but im really happy with the results, smooth with similar swirls to the body which is ok...
Its a bit wierd as i can see the rainbow in my headlights
credits to J, when i was sanding my lights at his house, he sanded a bit of my weds wheels and the metal stick that holds the bonnet up.. and for letting me use his mothers metal polish and buffer..( you happy man ? shii! )
