Orange crush, I appreciate your input as to you having owned one, the monthly cost to run the fan, and that there was filter that covers the fan. If this cuts down on dust and up keep it will be a plus. I just want to seal it up in this portable garage after I have completely detailed everything. It would be used in a garage so that should cut down on some mositure. Thanks to all my fellow forum hot rodders who have guided me in the right direction!
