Applied to garage floor after applying Ghost 4500. The 8505 is still curing. However, a little water from condensation from car a/c and beaded to the top. So far its outstanding.

Too soon to tell
Application went well. Has only rained 1x since application. Is working well now... want to see how long it lasts. If it holds up well, it's a 5 star!

Great Natural-Look Protection!
This product provides excellent water beading right after application without altering the appearance of the driveway at all.

I reached out to Ghostshield and told them what I had if the 8505 or 8510 would be compatible with whats already on the concrete short answer they said they didnt know. So I bought a small test bottle of 8505 to test. It worked and great so I bought the ...
