i was wondering what to use to cover up my garage, if there was like plastic covers i could buy somewhere to cover up my garage so i dont get any overspray anywhere. the only thing i could think of is like cutting a whole bunch of bags in half but i dont think that would work very well, so i was wondering if they sold like long plastic pieces anywhere that i could use to cover up my garage and stuff

and where could i pick some of this stuff up

 

go to any hardware store and get "drop cloths", you can get plastic or canvas ones. dirt cheap.
