Thanks, Very informative, but it turned into Porsche talk.(not that that's a bad thing!)
So I'm quoting him here,(hope he doesn't mind),this is what we want to hear!
"So The floor has seen a lot of heavier duty usage lately, beyond the typical detailing use.
The floor stood up to the abuse very well. I did a lot of fine tuning and it felt like I jacked up the car 100 times, so there was a lot dragging the jack and jack stands around. The paint is very tough and handles mechanical wear very well.
There were definitely a few spills, but I didn't let them sit too long (just out of habit )
The floor is not what I would consider slippery when wet. Its not like having stone grit in the paint, but its also not like your typical paint that makes you tread carefully.
Now 2 years since doing the garage. Still zero hint of hot tire pickup and looking as good as day 1. I'll be posting some updated pics soon. "
So, between this comment and your comment/tip on reducing the roller marks(in another thread)...I'd say its looking really good!
