Protecting equipment from damp.

[pitchfork]

Hi,
Me and my band practise in my garage and our new gutarist wants to bring his pa round for vocal use which i have no problem with but i'm worried it will get damp. i leave the drums out there and sometimes they are wet or damp when i play them.
Its got a thin filmsy metal door which i'm soon going to pad with a duvet to give better soundproofing.
The garage is also used as a gym by my dad so i can't do anything to crazy with it.
What can i do to seal the garage better?
Cheers,
Ross

Put draught excluders in, maybe. Keep the PA on a peice of ccarpet or somehting as opposed to on a concrete floor, and don't leave it touching the wall.

I guess.
