Sk8 has pretty heavy clear on it, so you might get away with t cut and a polish..
But, the last few ive done I either blasted back to steel and sprayed, or had dipped to remove the finish and sprayed. This was because corrosion has started under the clear....worm trails....
But, you may well get away with a good rub down and respray, but if you have corrosion it needs dealing with or it will just keep coming!
Imho, once the clear coat starts to go, they dont look brill...however you try to polish/ disguise them.
Got any photos?
