Negative Positive
Title: Great, with one caveat....
Review: I work with a lot of MDF and this stuff is great to seal mdf and wood. What I've noticed is that even though you can recoat within the hour, you really really need to wait at least 2 days if not 3 in order to sand. If you sand before your finish will not be quite as smooth and your sand paper will clog like you wouldn't believe. Just wait the 2 days for it to cure.
Is the review positive or negative?
