There always seems to be something new, something better, something new shiny and bright, and gotta have, or something that "works" like nothing before in its application.
This year I switched back to using NuFinish polymer sealant on my RV because the price of Mequires' Mirror Sealant 21 has gone through the roof. NuFinish was one of the earliest polymer sealant "waxes" on the market and I had great success with it starting in the 80s during my boating years, I continued to use it when I bought my first RV. After using NF this year and re-discovering how easy it does go on and off I wondered what made me switch to Mequires' in the first place. In the past several years ceramic sealants were the rage for that glossy mirror-like finish, now that is being pushed aside by a bunch of other new miracle sealants.
