I am getting ready to paint a sandblasted mechanics truck bed and the owner asked me if I could get on with the job? The temps here are 50's daytime and 30's at night, The shop I will paint in has no heat and I said it was too cold to do any paint work in these temps. Any advice from you guys is appreciated. By the way the shop is not mine, My shop will not fit the project so I have to do it at his dirty, dim lights and no dry air!
