Trumpeter 1/350 USS Essex

The deck seams aren't that bad, they're split on the actual deck seams of the real ship.
I would suggest assembling the deck on a flat surface, inverted, to make sure the seams are as tight as possible. Once dry, flip it over, tape off as close as you can get to the seam on either side, fill carefully, then wet sand carefully. Once it's to your liking, remove the masking tape. Re-scribe any small details you may have obliterated while sanding.

I agree with Geoff54. Why can't they mold a one piece deck just like the hull. Sanding down deck seams ruins the detail.

I've been playing with those seams for months now. I just can't get satisified with them.

There is another way to fill that seam.To do this you will need a pipette and some warm candle wax.or a flat stright edge blade.Take the warm wax with either a pipette or blade and fill seam.After it has dried take your flat blade and go over the dryed wax scraping the excess untill smooth.As long as the wax is warm to the touch and not hot,it will work and not melt the plaistic.Digger
