Word of caution:
It has been my experience with Launch Pad kits that the blsa supplied is usually just enough to do the job, no extra.
This results in a need to sometimes cut fins in a grain direction that is less than optimal. Leaving weak fins.
TLPs cure is to coat the fins with thin CA adhesive.
This works great and results in rock hard fins but some tips to do this so you don't get frustrated.
Work in a well ventilated area (the fumes are terible)
Apply the CA before you glue the fins to the rocket.
CA will leave ripples and globs that will have to be sanded off.
CA is hard to sand and is best done with a block with the fin laying flat on a work surface.
You will notice when you put CA on one side of the fin it will bow.
Don't worry when you put it on the other side it straitens out.
There are other methods of stiffening a fin. Look in the Techniques
section of this forum.
Good luck with your Alarm
PS: CA will stick to wax paper but better than gluing your fin to your workbench
