Brightening the exterior finish

I had great luck with Red Max Pro and later Zep Wet Look by the same company. It CAN check or show defects if applied over remover and not on a pristine clean surface. The process is well documented and lasts much longer than a Maquires wax job--not forever though. It is important to throughly clean with Bar Keeper's friend--amazing how it takes off the oxidation--especially if you can find the white 3m pads that are finer than the green, then wash with a strong cleaner (TSP is recommended) and rinse well. The floor wax needs about 4 coats to get the shine. It can be renewed with another coat in a year or so, or removed and the process done again, maybe every 2 or 3 years. I had a bit of checking on the overhead after using the remover--but nothing terrible. The stuff didn't save my poor decals though. They have continued to crack and peel and I will have to tackle them someday. I recently read that cement sealer works in the same way too.
