About treated wood.
To answer your question: Yes, you can apply a coating to pressure treated wood and then use it. One issue is finding a coating that will adhere to freshly treated wood, most comes from the lumber yard in a high-moisture state so most coatings fail to develop a good bond.
I've repaired a few trailers with frame rot and mostly used conventional lumber. In some areas like inside wheel wells and in areas that will typically see some moisture, I've opted for ACQ, cedar, or redwood. I think that keeping the moisture out with a continuous sealed covering is more important than using treated or special species.
I'd suggest that when you get done rebuilding the affected area, you perform a pressurized leak test. I used many types of sealants and was anal about where I used them but still had a few pinhole leaks when done on the last one. The leak test will turn up everything.
