Hello,
There has never been, and most likely will never be, such a thing as "never paint again".
Companies like this have come, made their fortune, and gone many many times in the past. They charge a ridiculously high price to apply some coating they hard-sell with graphs, charts, etc. They offer a 'warranty' that seems amazing until you actually read the fine print. Then after 5-8 years either file bankruptcy or completely disappear.

There is no better option than a quality paint job using good materials (100% acrylic), applied by a true professional painter (not a spray and blow hack).
