Getting a bedliner!

[Project1970]

My dad's getting me an Inyati spray-in bedliner for my '70 as a sliiightly early birthday present. (Appointment is Fri, my birthday is Sunday. Heh.)

Anyway...I'll probably still call them to make sure, but is there any prep work I should do, aside from maybe just washing the bed? I want it sanded out at least some, the last coat of paint is kinda crappy and they painted over stuff they should've washed off, like a bird turd, and some spilled superglue residue that should've been sanded off if a block had ever touched my truck like they said it would...
