Wet sanded and polished some more today. I'm almost through with this phase now (excluding the needed touch-ups), so perhaps I can now get busy on wheels and interior. Far from perfect I realize (I can be very harsh with my own work), but not too bad really, I think.
Thanks for the support, fellas. No, I'm certainly not going to give up. If nothing else, it'll (I hope) make an interesting display piece, and I'd really like to get something finished.
