its the kind of kit where you have to get the seam right or its the first thing you will always see.
a few small sections I have gotten the seam to disappear but I still feel a slight bulge and when I did a test prime over the seam to see how it looked - well the seam still shows.
I've masked very close to the seam so I would not have to take off a lot of extra putty - maybe that is the problem. I might have to sand down the higher side instead of adding more putty, but I have to be very aware of feathering out the sanding so I don't leave an obvious line...
One good thing about subs with this kind of center seam though is that you always get a second chance with the other side. If this one fails, I can give it one more try.
at midpoint. The hull's not that much longer than the 'one piecer' 72nd RoG U-Boat's hull halves. I wish Moebius/Platz had gone that route, even w/ the req'd much longer box and perhaps added cost.
I backed mine w/ a bunch of 1/4" x 1/2 x 12" plex strips after chopping up gaps in all the interior molded bracing. Let the glue set for a couple wks and then had at it. It was an OK kit fit but not OK enuff for me, so lots of thin coats of putty and Mr Surfacer, constant eyeballing down the length. Lots of checking w/ a long steel straight edge. I've wanted a lg scale kit of Seaview for a long time so I wanted zero traces of the joint line and for it to look straight, true, like a one piecer.
