I prefer the Black Super weather strip adhesive...but it is NOT cheap.

I think this would be a fantastic way to build walls for, say, a teardrop trailer. I don't think it's a great idea to use it for cabinets.

For most people, it's down to preference. Some don't mind applying wax more frequently, so a traditional carnauba wax is ideal. Others prefer a synthetic base sealant and carnauba spray wax as a topper. You have endless choices, depending on your climate and situation. For starters, you might want to try a hybrid spray wax like Meguiar's Hybrid Ceramic or Turtle Wax Seal and Shine, both are easy to use and should be available locally.
