Another excellent suggestion! Thank you, GearheadGreg. 😁 Following your recommendation, I will put a screened grommet on the side of the trunk chassis opposite the fan, where gas vapor odors collect (none detected in the cabin or engine bay), in addition to a HEPA filter, and reverse the fan flow. Humidity in a tropical environment is constant, often about 73% throughout the year in my location, although it is far lower than in Florida. There is nothing I can do about that; thus, introducing humidity into the dust and rust-free bag will somewhat counteract the desiccant bags inside and the Zerust® anti-rust chemical integrated into the material. (For your information, this fan operates at around 53 CFM on high.) After 44 years of using rust prevention techniques including extensive waxing, periodic pouring of protective substances, and avoiding water cleaning in favor of quick wipe-downs with rapid waxes, while also refraining from driving in the rain, she remains intact!
