Yeah, no sweat! I try something new each build. Keeps it exciting. =] Preshading is certainly a working method, but I've been finding it's not the only way to go about it. So if you haven't done it by now, there's still plenty of things to do. Some postshading can fix up whatever you have in mind. If you had any specific questions, just ask.
Speaking of new...I'm finally beginning my build and I'm starting off a little different. I'm first building the AccuMin P-51A with JJ England. This time around I'm sanding the inside wall of the cowling paper thin so I can try to replicate what you see with the cowling pieces bending and warping after being replaced so many times. With a new blade, I'm cutting very carefully into a couple of spots as seen in reference photos. I'll have to go back and tweak this a little but I feel pretty good about it. What you see now is just getting started. I'll show what I've fixed up after. I've also opened up the vent on the right cowl and thinned the intake for the carb to bring it closer to scale.

Dropping a Squadron canopy in on this one doesn't seem as easy as just "dropping it in." Releasing it from the mold wasn't too bad. I am getting a little better at this. It shouldn't be rushed, but somehow I always do. This time was nearly perfect. I used the canopy over the top of the fuselage to make a mark for where I'll need to cut. This was taped off and marked with my new blade. I hope to not remove too much from the kit, but any fit issues with be filled with plastic strip. Fingers crossed. =] Still trying to figure out whether or not I want to open up the canopy.

That's all for now. Soon to be scratching out the cockpit controls and radio equipment.
