Ive polished mine and 2 months have passed and still shining
Anyway the hard part is to remove the paint ive used a chemical it was like gel for hair and 10 min after applying it burns the original paint its forming bubbles because the chemical is very strong and its designed for removing paint, and the hardest part is to sand them after with you will sand them takes aprox 1day for one rim you will polish them with polishing paste and its very essential that the polishing paste is of very high quality because ive used 2 different types and they gave different result. Few days ago ive bought sonax and i will try it maybe this week end, so the bling bling effect comes from the quality of the polishing paste.
