Seems to do its job and strips well. I give it a five star.

Great product! The 2 step process is easy and effective. The prep removes any built up residue by lightly scrubbing with a blue soft scrub Brillo pad and a quick rinse. The final step of applying sealant adds a high gloss, like new sheen. Very impressed with the immediate results. Anxious to see how it holds up over time.
