thanks for the reply!

the VOC(smaller can) and the Quart(bigger can) have different part #s...

on the black, i use the small can that i bought from home depot with says "Stop Rust", but at Lowe's the same can of gloss black, it says Professional on the logo...so i was wondering if i bought the wrong paint...

however on last coat, i was wetsanding from lower grit and ended with 1200grit...so i am guessing i should've gone even higher? 1500 or even 2000? coz the buff barely bring out any shine...a very crappy shine...
