Smeagol,
Yeah, I hear ya. The seams on this kit are kind of lousy. I was really disappointed with the fit of the kit especially since it's a new release. I recently did Academy's CH-46 and that fit great.
Anyway, here is what I did to fix those seems. First, I loaded each seam with Tamiya's Liquid Surface Primer. Sometimes it took 3 or 4 applications. After it dried, I used Testors Easy Lift Off Paint and Decal Remover to smooth out and remove excess primer. There's still a slight seam there but I guess this is ok since the plates were riveted together. If you look at my pictures, you'll see a gray tinge in some areas. That's the residual primer.
It seems like Academy made this kit unnecessarily complicated. Maybe they're trying to compete with Dragon in terms of complexity. Just a thought...
I know this kit is more accurate than Tamiya's offering, but I feel like I'm "polishing a piece of poo" here. This is kind of funny. I was working on the kit at the kitchen table and my wife said she was going grocery shopping and asked if I needed anything. I said "Yeah, some poo polish". She just looked at me with that special "wife-look".
