Did More sanding ... about as good as it’s going to get on my watch .... It’s not perfect , but will serve the purpose ... fairly streamline so should tow pretty easy ... especially with that long tongue ...

Minor difference now , not worth an extra picture ... Still need a ‘filler” for leveling ..... GS doesn’t sand worth a hoot ... grrrrr!!!
W2 , I thought about that , but could run the skin up to the bottom edge of the “ridge” and then put a central strip overlapping all that on top ... There will be a seam at the top anyway ... my canvas is only 60” wide ... two seams really ... No worries ...I’ll just paint some fake rivets on the seam edges ...

And now , to the back end ... door framing first ... Got some nice #1 clear Pine 1” X 4” ... that should do ...

Then I need to get More foam ... may go Blu or Pink in the back , just for convenience... couple sheets probably ...
