I am going to be building my bench this weekend and was planning on putting it in my garage. The garage isn't heated or cooled. Will the temperature variability be a problem? How will it affect powder & primers? I am thinking of buying two insulated cabinets to store powder and primers. The alternative is to put it in the house but I only have space for a 3 foot bench in the house, whereas the garage has unlimited space. Where should I put the bench, any suggestions would be a big help.
