I completely agree with Big Kakuna's original post and then WB1994's point on 2 layers of glue on each surface before sticking back together.
They both already said it, but I'll stress these points again:
1. I apply a light coat on each surface (after you've sanded each surface and cleaned with acetone). Then, allow both sides to COMPLETELY dry. This means being able to put your fingers on both surfaces and have it not be all gooey. If you have globs of goo, it could mess it up. Once both sides are dry, repeat applying the contact cement (a thin coat). Let dry. Then apply. When applying on the bond rails, work from the top down to the sides.
2. When cutting the excess turf on the sides, you need to think of the water flow and force on your rails. You need to decrease as much surface area as possible for water to grab onto. Therefore, cutting the turf at an angle instead of 90° is integral to this job and many people don't do this. Use a sharp razor blade to cut and it'll go so smooth and easy.
Enjoy!
