It works well and is worth every penny
This stuff really works well. I did a couple of coats an still had a bunch left over. It really does help to lock in the foam. It dried very fast. I would 100% buy again but I won't have to because I still have a bunch. Great deal. Great heat retention. Easy to apply. Really toughens the foam, and it comes in a big bottle!

Skeptical
Was a little skeptical because it came clear instead of the other rigidizers that are blue. But worked well and cured up in a day
