If this is not ok to post then let me know, but I have a question that I feel can only be answered here. Question: Would it be possible to heat a 50' semi trailer frame to roughly 400F through electrical resistance, I know it would require a lot of power but the reason I ask is because I am starting a powder coating business and I'm not about to build an electric or gas oven that;s over 50' long. In my mind I'd think a large power supply such as a massive welding machine (maybe?) would be able to provide enough power to heat the trailer. Now this trailer is not boxed in, they are used to haul timber and 100" logs, as I live in logging country and the salt eats away these trailers like nobody's business. Thanks in advance.
