Your first coat on the turf normaly will suck into the turf so I do 2 coats each side and have never had any problems
Yup. You will notice this the first time you put the glue onto the turf, it tends to absorb a good amount. A second coat on the turf is good insurance. I sanded both turf and ski with 60 grit, two coats of glue on turf, one coat on the ski. Used the heat gun the speed up the drying of the glue and to round the turf around the rail caps, foothold area and bond rails. The heat isn't always necessary but it definitely helps. Careful not to heat and stretch it too far or it will pull as it cools.
Really make sure the glue is no longer wet before placing the turf, it's gotta be dry and tacky. I made a mess of my side rails cause of this, was not fun.
