Good point Matt!
As far the dew I'm gonna throw the hood on after its painted to protect when I paint the whole car on buying one of these from harbor freight. Its gonna double as my garage and paint booth lol
My wife and I bought a 10 x 20 from Costco for about 228 and we were able to put it together in about a half hour with no tools and it's lasted for about five years next to the house....
