I'm not a huge fan of petromat
I've belonged to two clubs with petromat, pretty nice when there new. After a easy california winter you start getting highs and lows on the runway where the water sits.
Then the sun starts take it's toll and the runway starts to fray... the spikes start to loosen up and lift. The wind starts to lift the runway...

couple years you have a pretty bad runway... rough on retracts and landing gear
