All my information comes from NGs. I can't seem to find anything official on the net. (let me know if you come across anything) Here is what I think so far: Buffing Metalizer is a mess. When you first spray it the flecks of metal go everywhere. After 20 min, use a cotton cloth to gently buff the Metalizer. Do not mask as it will marr the metal. Do not handle cause each time you handle it, you rub some of the metal off. Do not clear coat cause it will ruin the finish. The proper order is Paint, sealer, buff, decals. Lots of people have problems.
OK, that is all I found. That is 100% reading and 0% practice. But it looks like you did great with it. You used the Titanium Buffing Metalizer right? Well, anyway, you have given me faith to try it oh Jedi Master. I'm going to go get a can tomorrow and test it on some spare tubes I have around the house.
