im planning on refurbing my beat up strat copy. the pickguard has a lot of wear on it including scratches, some of which are fairly deep so that its pretty visible. so heres a question, can i sand the pickguard down to smooth out these imperfections?

try googling on how to remove scratches/polish plexiglass or lexan

I'm pretty sure the same methods would be applicable to your pickguard
