Awesome A-body air dam for under $30!

Not to derail the thread, but are those the Amazon garage tiles? I like the way they look, but always wondered how they would hold up to weight on a small surface area, like a Jack or engine hoist. How do you like them?

They are Race Deck tiles, I've had them about 7 years now. The solid tiles hold up good, a lot have burn holes/marks from welding and heavy grinding. Jacks and jack stands don't damage them any. On the other side of the garage I have their free flow vented tiles, when I use jack stands under my pickup they have dug into the ribs slightly and left divots. A piece of cardboard under the stands gets rid of that issue. With my cars weight, there is no issue. I've spilled lots of fluids on them, it all cleans up easy, although a leaking gas line ended up warping a few tiles after a few days of gas sitting on them, but the company warranties them no questions asked.
