I have several vehicles to take care of. A tractor, Trike, motorcycle camper, 4 wheeler, two cars and maybe use on some other non vehicles? I like the looks of the Megs mt300 Kit here (480 value for 279) Is that too much for personal use or not a good machine for what I want to do? I have not owned a DA before. I did apply a coating or sealant by hand before. NOT a good way to go.
