Nice progress, my friend @eb801!
The bays look nice and busy!

Nice improvement on the wheel wells, Eric @eb801

The fitting of the wings look great as well, Eric @eb801

Cowls and Engines Installed
Moving kind of slowly here as I am working on another build simultaneously that distracts me from this. The resin cowls and engines are installed. I was going to install them after painting but the cowls need a bit of filler and some minor modification to get a proper fit.

A problem that I just encountered is that I am having difficulty getting the paint to stick to this white resin. I first sprayed the inside of the cowls and nacelles with Alclad lacquer primer but that totally peeled off. Then I sprayed the area again with MM acrylic zinc chromate with no primer and had the same result. After a good soaking in sudsy ammonia, I tried a third time but switched to Vallejo acrylic and so far so good. I am worried about the exterior of the resin nacelles. I am afraid to do any masking in that area as I don't want to risk the paint pulling up, as I am sure it will. Paint shop is next.

Coming along nicely, my friend @eb801!

This is really looking superb, @eb801.

@holzhamer, @johnb, @tcinla, and @fiveten - hey thanks for the input and encouragement fellow modelers! At the moment I am giving this Boston a coat of primer since I am working with different colors of styrene and resin. Also easier to find my mistakes and make corrections. I will be using rolled up "worms" for masking the North Africa desert camo using Vallejo middlestone and dark earth for the topside and azure blue for the undersides and early markings yet to be decided.

Onwards to the Paint Shop!
First I sprayed the canopies with Tamiya acrylic RAF dark green.
