I have heard some good things about the cyclo sealant. Got mine last week but I haven´t tested it yet. Will test that sealant with Chemical guys M-seal.
I doubt any sealant out today could last 12 months...but there are quite a few that claim they can. Most of those durability claims mean nothing...but then again, I've never used the stuff so I don't have anything to base it on.
Today I helped my friend to polish the roof and hood on his 01 VW Passat,black metallic pearl. First with PO91L and the PO85RD and then sealed it with the cyclo sealant. Very nice to work with this product, and a little goes long way. We let it dry ~45min and the buffed it of with MF-towels. It was like Menzerna FMJ, VERY easy to wipe off. And the surface was so damn slick. I was surprised. And I am not expecting 12+ months of protection but the first impression was very good.
Yesterday I sealed the washbowl with Chemical Guys M-seal. Had no car around and I wanted to test it on something
