Great project, Mike! I think this kit still holds up well today. This was from Monogram's golden age.
Yeah, the canopy. It's like the canopy on their P-47D bubbletop, too. I use the kit canopies but I pose them open. Then the fit isn't really that noticable.
Speaking of undercoating yellows, I use white, myself. I do that for reds, too. Whatever we use, it really does help to base first. I've never had a red or yellow paint that didn't benefit from an undercoat.
