If you're looking for thickness and weight, I used this horse stall mat. About 3/4" thick and takes 2 people to handle it. As heavy duty as I could find.
Added my Tractor Supply horse stall mat after a little trimming. VERRRRY HHEEAAAVVY and worked out well. 44.00 well spent. Smooth on one side and texture pattern on the other side.
Got a box of detail supplies from Autogeek. Going to clay bar the Ranger and acrylic seal then work on my wifes black Lincoln. Started on my roof and hood. had a little rail dust but not as bad as some I've had in the past.
