Just saw a 737's landing gear after switching from the old sealant to that new polyurethane stuff, the difference after a year is crazy.

Wow, that new sealant really holds up. The old stuff always looked cracked and dirty after a few months. Big improvement for maintenance crews.

Reminds me of the caulk in my old bathroom. Had to redo it every year like clockwork. Some products just get it right.

Ever notice how the good stuff just looks new for years? My old truck's bedliner has the same deal.
