Another thumbs-up for the (previously) Honda polish. I buy mine several cans at a time online from Wingstuff, but I'm sure there are plenty of other places to find similar deals on it. One note of caution, however, and this has nothing to do with the polish itself...just know that this finish is somewhat soft, and if you rub too hard, you will leave a smooth. Ask me how I know!
When I first got the bike, I didn't like the Honda letters on the front garnish, so I removed them. I did it the "recommended" way, heated them up with a hair dryer, then used dental floss to separate them from the bike. The problem was removing the adhesive residue...I elected to use WD40, but I still had to do a lot of rubbing, and yes, I did leave smooth spots on the finish. You have to look real close to see it, but I know it's there. So just be aware not to rub too much and you'll be OK.
I have been using the Bike Spirits polish since I got my first Goldwing 10 years ago, and it's bulletproof. I use it on everything, body, windshield, it works great, and I've never scratched the paint. Just spray it on, let it set for a few minutes to loosen the bugs, and wipe if off. I do use two rags to remove it. One for the really dirty part of bug removal, two, a clean rag to remove any residue.
