Don't know if anyone's tried this stuff out; we picked up a can of it after reading a review recently, which reckoned it was good for brushing as well as spraying, and gave the mid-hard kind of finish we wanted. Trouble is, now that we have it, the stuff seems nightmarish to apply - we've tried a number of brushes, but it always seems to go wrong, and ends up crackling (so it looks like shattered glass almost).

Does anyone know what we're doing wrong with this, or how to prevent this from happening to our finish?

Cheers.
