Ken and Rick, thanks, I'm not the biggest fan of PE, but these bits really work well on this model.
I managed to get the guns made and installed, the windscreen attached and the exhausts on the engine.

Now I am a bit annoyed because the mold lines are still visible on the ammo chutes and the exhaust after having scraped with a #11 blade and sanded with a stick. I thought for sure I had nailed them and then my 12 megapixel Nikon tattletale showed them right up like they had never been touched. (Resulting blue language scared the dog, but didn't do anything to the mold lines.)

So how do the experts deal with mold lines on small parts? I find scraping only works until the parts being treated are small and delicate enough to be hard to hold firmly. Pretty much the same sanding. Again holding the part limits the size of part I can effectively use my Flexi-File. Other than making narrower sanding sticks, which I will do, anyone have any effective techniques for loosing these pesky lines.
