Brilliant results
Honestly impressed. I've tried a few competing products in this category and this one out-performs them on application speed and final gloss. The Menzerna formula goes a long way per panel — a little really is enough.

A solid addition to the kit
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.

Outstanding for the price
Used this on my daily driver last weekend and the difference is immediately obvious. The hood looks like glass again. Easy to apply by hand, didn't take long, and clean-up was simple. Recommended.
