This is the sort of half-assing I can get on board with. So if I were to treat all cut ends with deck protect (including those ends of cut frame lengths that will be screwed together) and then give the finished deck a coat (on the rationale that the side facing the weather is going to do most of the heavy-lifting re water repelling) I might not be entirely negligent?
Given the effort of the job, personally I'd slap a load of something extra on all the joists and bits where water could linger.
I'd be less worried about the top. Plus you can probably knock the top out quite quickly with a spray gun or shaggy roller as some point down the line.
