Polish or make them silver again after paint?

After you touch up or paint the cylinders and/or heads, lightly sand all the fins with 240 grit paper or emery cloth. Then sand again with 320 and then 400.

At home depot you can buy a light use polishing kit that comes with compound and some buff wheels. It works with a drill.

Run your engine and get it warmed up. Now buff the fin edges. It will get compound on the fins that will be a pain to get off. go light on the compound to minimize this issue. I recommend doing a test spot in a hard to see area first.

At the local autoparts store they have a carb and parts cleaner that comes in a gallon paint can type container. It says Environmentally safe or something on it. This works extremely well on removing polishing compound. Again test this on the test spot. This should be used only after the engine is fully cooled down. DO NOT APPLY TO HOT ENGINE. This cleaner will leave a residue that comes off with regular cleaner that you would use on your bike, I recommend BikeBrite.

Again it should all be tested in a safe spot in case you don't get the results you were looking for.
