Hi stikpusher, Eaglecash867, thank you so much for the advice and encouragement! I have learned so much from this forum. This is one of those things that seems so obvious in hindsight, I feel like a complete idiot for not thinking of it. But I am sure gloss coat and decal solution will make a huge improvement. I also believe soaking the decal longer might help. Even though it was laser printed, I was so afraid of the ink running that I barely let it soak for 15 seconds.
So, I have a decision to make. Invest more time and effort to improve the bomb decals, or regroup and fight another day. Tbh I am reluctant to put so muich effort into bombs, I will probably get on with the rest of the build. However, I think my next build will be the P-47D flown by Major Glenn Eagleston in France 1944. I don't think I will find a kit with those markings, Furball has a decal set with markings for 4 or 5 different P-47's including Eagleston's. But it is around $20 plus shipping. So I will try the laserjet decals with the tips you provided. Hopefully the smoother NMF finish will help.
As far as the bombs go, my main issue is opacity, the words came out too faint. The photo was taken with a flash and zoomed in, so the words are readable. But to the naked eye the words are barely visible. Imo there is not much point in making the words unless you can read them. I sized the letters to be about .028" tall, which at full scale would be 1.34". These are way too big compared to actual photos. If I make the size even close to accurate, they would be way too faint and small to read. Plus, the moderate weathering I am planning will further obliterate the words. I think I will use the remaining decals I have already printed to practice the tips on a test A-10 I have laying around.
Your experience with the inkjet is pretty similar to mine. Also, last week I had the Amazon Sunnyscopa in my cart and was in checkout when I saw the shipping was $5.99. So I emptied my cart and bought Koala with free shipping from Walmart. I saved about $5, but maybe got an inferior product. Hopefully it will work better with the tips.
It has been around 3 weeks since I ordered the Mig Ammo acrylic SEA camo set. I cannot get results with the tracking link, so idk where it is. If it doesn't arrive in a couple weeks, I might order MRP from Spraygunner or Sprue Bros. Even if I end up receiving the Mig Ammo, I plan on building other SEA camo planes, so it won't go to waste.
