I love menzerna products, and these were no exception. PO83 and PO106 are a great combination for cleaning up minor defects with my Porter Cable 7424 random orbit. If you have anything you would describe as a scratch, or etched water spots, the power gloss 1000 would be a good first step instead of PO83.

As far as the power lock sealant goes, only time will tell as to the durability. Finish was as good as the old FMJ, but I do miss FMJ's ease of application. The power lock is a little on the thick side (still easier than carnauba, though).
