how to fix delaminated tip/tail
you'll need:
a tube of epoxy (10$?)
a bolt and a nut (2$)
go home, open up the 2 sheets and remove all crap thats in between the two delaminated layers
take a fine sandpaper and sand the two surfaces down a little, removing all loose crap that might still be attached...
then mix your epoxy and smear it in between, spreading it out evenly, making sure that especially around the edges you have a waterproof seal....
then clamp the two pieces together and let em dry 24h
then remove clamps and drill a hole in the tip/tail and put a bolt and nut through it for enhanced badass and strength ....
so i dunno how much theyre gonna ask you, but that shit is fixed in no time if its a simple delam ....
and costs virtually nothing on repair material, just some epoxy ...
