Better than I expected
If you're on the fence — pull the trigger. The depth of finish after a single application surprised me, and water beading was textbook. Lives up to its reputation.

A solid addition to the kit
I picked this up after reading the review here and the results were exactly as described. Bilt Hamber clearly knows what they're doing — application was straightforward, the finish is even, and there were no streaks left behind. Will be keeping this in the rotation.

Works well, takes practice
Works as advertised on light to moderate jobs. For more demanding work I'll still reach for something more aggressive, but this earns a place on the shelf.
