Cheers on that, I only have the PE for the underside due to a promotion when I bought it. I think it will be fine if I use the plastic and incorporate some of the larger PE.
I did the same thing as you, I built the San Mateo a wooden plank on hull ship by Constructo. Very time consuming, especially since I had never done one before. I am hoping on getting a cutty shark to do next.
After it was done I built some quick Fine Molds kits ,2 Tie Fighters, a Y-Wing and the Slave 1. Had to get some small stuff done. Now it's back to another long build... I still have the new Bismark to build as well!
