I assume you mean a smooth foam applicator, and yes, that would be fine.

#20 is also mild enough for monthly use.

Might want to use a foam or microfiber applicator pad when using M20 Polymer Sealant.

You should not run into any problems applying M20 every month either.

As I recall, several folks here on MOL use M20 as their winter sealant and report good durabiilty. Perhaps those individuals would like to share their #20 testimonies with the brethren. If we haven't yet applied our winter protectants, we are getting darn close to doing so. M20, perhaps topped with M21 or NXT might be an excellent winter combo.
