Feel for you Troy. Airliner paint finishes is a entirely different skill set I understand. Not into building airliners (yet) myself, but can see myself getting into building some from the Golden Age - 30's to 60's at some stage. I have a lot to learn about achieving the best finish before then. In the meantime, I've been using my little 1/48 aerobatic aeroplane builds as "technology/skill" test beds. Much easier to experiment on little builds rather than stuff up big builds.
I've found Gunze/Mr Hobby flat white is a brilliant undercoat and polishes up nicely as well, same with Tamiya flat red, but it goes quite a bit darker when hit with a semi-gloss clear coat. I know the airliner guys use a lot of rattle cans which is fine on big builds, but not so on little builds.
I still have to decide on the best type of finish for my red & white RB-51 - I like Eric's polishing technique - that Comet was absolutely flawless!
Anyway, keep the faith and keep working on your techniques. What doesn't kill you makes you stronger!
