It's dipping down to the 30's here in Minnesota, and I'd like to still be waxing in the next few months. Any recommendations for garage heaters? I'd like to stick to something as safe as possible, a friend and I have used propane heaters a lot years ago, but I'd prefer to use something where I wouldn't have to worry as much about carbon monoxide or explosive gas.
Are infrared heaters effective for detailing? Are electric heaters (whether older styles or infrared) too costly for a detailng job? Or would you charge extra if getting paid to do it?
