3. Water based polyurethane varnish - like TDS Hauthane HD-2209
4. press or clamps
5. Heavy grit sand paper 60-80 grit
I MADE IT AT TECHSHOP!
Step 1: Build a press or get some clamps
because the water based varnish proved to be the best glue for this application a manual press or clamping pressure had to be used instead of vacume bagging because the rawhide and varnish need to be exposed to air to dry. MDF is the perfect material to protect the rawhide and disperse clamping pressure because it can let air pass.

Step 2: Prepare the substrates for bonding
in the photo's I used a DA sander with 60 grit sand paper.
Th polycarbonate was clear before sanding, sand it until frosted to remove the hard top layer.
clean off the dust.
Step 3: Glue and Press
clamp in the center first then work your way out to push air out.
