Hi, I'm a first timer here and I'm resuming modeling after about 50 years. Got about four models (3 were Monogram) under my belt at this point and I'm presently working on the Monogram P-51B Ding Hao, copyright 1999, kit # 85-0136. The box has a Monogram Classics label but is otherwise identical to the Ding Hao you have posted.
The fuselage halves don't fit well even when the alignment pins are lined up and a lot of sanding is required and the canopy falls a little short on fit. It's not as bad as the Monogram/Revell JU87 which had fitting problems so bad the law of diminishing returns set in and I canned it. The kit at this time is still doable and I'm approaching it as a chance to improve my skills. Had to remove one side of the interior details to allow the pilot to fit in because the fuselage halves wouldn't come together. As for the instrument panel the decal details were to faint to use so I put a white base on the instrument panel, followed by black and sanded it using a sanding sponge just enough to reveal the instrumentation.
I'll try that Future wax suggestion next time
