Ok, I finally have some progress to show... first ship in 25+ years, came back to the hobby last year

This is the 1:72 Revell PT boat, done OOB for now.
Hull/deck primed.. fit was horrible, I had to line up as best I could and Dremel-sand the portruding lip. I putty/sanded the joint, still have some coarseness, so I prepped the joint for more putty/priming.
Some parts glued to structure, the portholes/windows are covered, some pictures are shown 'shut", with added steel plate in place, but others have it "opened" with glass...
Should I leave as is, or open the plastic and put a "window" in place?
While sanding the joint, I was not careful and got the hull scratched... need to use some liquid primer to fix the scratch:
A better view? (sorry, having problems posting pics...)
The propellers, so much flash, I felt I was "sculpting plastic", getting the prop from the sprue, should have taken a before/after pic (this is after):
Should I look for a brass rod for the prop shaft? instead of the plastic one?
Another piece that I spent an hour chiseling the flash away, the mufflers (see all the flash around it?):
I will try and drill a hole on the exhaust, see if it look better that way...
Any comments or suggestions welcome, also about the posted pics, seem large to me? Thanks, james
