Ultra uses:
- Coke + aluminum foil technique for chrome.
- sometimes the chrome is so bad that is better just sand it with 600 grit wet sand paper and polish the heck out of it.
- If crome is flaking one solution is sand it out to smooth the surface and then polish the heck out of it, you might end with a darker spot in the chrome but the surface will be smooth.
- sand (slightly) the paint with 600 grit wet sand paper, then 2000 or 1500 wet sand paper and polish, that will get all the impurities incrusted in the paint job off, it will get rid off some superficial scratches aswell.
- For bolts and nuts with rust I been mixing the naval gel technique and after wards I drop the stuff in a tapleware with coca cola for an hour, then rub the rust right off with paper.
