I have noticed that both M21 and NXT when just applied doesn't look like it offers much protection, but wait a day when it cures and then I can see an thick polymer coating covering the paint, this is especially noticable when you have a paint chip under to differentiate the contrast, you can really see how thick the sealant is as a sacarficial barrier. I'am convince that both M21 and NXT is a durable as Zaino or AIO and that beading is not a good indicator on polymer sealants.
