Anyhow, I hope that your finish experiments bear fruit - good luck. Derek Thanks. The Alclad "lacquers" come in two types. The "Regular" ones are definitely solvent based and etch into the primer coat, which is why they are tougher, while the "High Shine" ones like Chrome appear to be alcohol based and are more fragile. I've used solvent on both of them in the past and they come off easily, so solvent on decals is not an option. The key will be how good the decals are. If they are thick and/or won't settle down without a lot of Microsol, I will be needing a clear coat. If they are super thin like the ones I used on my P-38, I may be lucky.

scvrobeson Posted February 17, 2021 Share Posted February 17, 2021 If you really want a clear coat that won't mess with the metal, it might be time to try the 2K clear coat car modelers use. That should protect it, is polishable, and won't mess up the Chrome shine underneath. Matt chuck540z3 1 Link to comment Share on other sites More sharing options...

Just a theory, with the caveat that I'm wrong at least 50% of the time. Just ask my wife! Most of the clear coats I tried are actually quite good at what they are meant to do: Cover the paint with a clear, blemish free and shiny finish, just like the car clear coats. Most of the Alclad metallic paints look like they have tiny particles of metal floating in them, reflecting light like real metal does. I have no idea if it's micro-metal bits or pseudo metal bits, but it looks like metal to me floating around in the jar or airbrush. When I spray Chrome on the black lacquer primer, for instance, it looks a bit dull at first when it is loaded with thinner and other solvents, but as it dries, the shine starts to come through. The thinner is interfering with the reflectivity of the metallic bits in the paint, but as it evaporates, it no longer impedes this reflectivity. Clear coats do the very same thing. The reflective surface is no longer directly on the dried Alclad paint, but above it, so the metallic reflectivity has been diminished, causing a duller looking finish. Getting back to cars, there are many metallic finishes out there and while they can look shiny and beautiful, none of them look like real polished aluminum or stainless steel, due to the clear coats protecting the paint. And then again, maybe I'm full of $&#t!

Daniel460 Posted February 17, 2021 Share Posted February 17, 2021 Outstanding build thread! Thanks for the in-depth explanation of all your processes, especially in the paint area. Lots of great information. These century series jets are my favorites. I did pick up a Hasegawa F-104G/S on Ebay, it came with the Black Box pit and an Eduard interior etch set for $30. I also got the Daco book from Sprue brothers. Plan on starting it this summer.... Are you and Kev going to do a book on this build?

Thunnus Posted February 18, 2021 Share Posted February 18, 2021 Great discussion on NMF and the preparation that needs to be done BEFORE the metal color goes on. The clear coat issue is interesting. Since WW2 is my niche, I really don't have a need to show shiny chrome-like finishes outside of an oleo strut or two. But I read a build log at The Modeling News website and the builder mentioned Tamiya Lacquer Clear LP-9 as a something he's found to produce "the least visible impact to the metal finish of all the clears". HIs build (Kitty Hawk FJ-2) did not sport a shiny metal finish so I'm not sure if his findings apply to a highly reflective metal finish like Alclad Chrome but I thought it was worth a mention.

Thanks! This makes sense, so I'll try to find some and give it a test. The worst clear coats over metal are thick, like Future and the Alclad Aqua Gloss, while the best one I found so far is X-22, which I thinned a lot with Tamiya lacquer thinner. A clear lacquer, likely thinned even more, should give the thinnest coat and maybe not dull the finish too much. One key concern is what will it do to the Alclad, which crazes easily with solvents of any kind. I see another experiment in my future!

themongoose Posted February 20, 2021 Share Posted February 20, 2021 Hey Chuck here’s another clear you may want to add to your trial, AK Interactive Gauzy. One of the guys over on FSM got his and tried it out. Mine is still in the mail. Here’s what he had to say, although no pics yet - but I know you’d want to try it for yourself anyway if you think it has merit. “Well the Gauzy came in today and I shot it over the Alclad and I'm VERY happy to report no loss of metallic sheen. This stuff levels out like a champ leaving a glass smooth finish. I freaked out at first cause it was a bit gainy in a couple of spots but it just leveled out smooth. No pictures cause believe me, there is no difference in the metallic effect! “ chuck540z3 1 Link to comment Share on other sites More sharing options...

Meanwhile, back on this model, I haven't touched it for 2 days and by the time I start to put decal rivets on it, it will be 3 days. I learned from my F-5E (the hard way) that to rush the drying process, even if it feels dry, results in better finger prints than law enforcement can provide. I have also sprayed 11 shades of Alclad metallic paint on test spoons and ordered 4 more shades that I have yet to try, so I will have a full comparison of all of them as soon as the new Alclad lacquers arrive. Stay tuned, Chuck Edited February 20, 2021 by chuck540z3 Brett M and USMC Herc 2 Link to comment Share on other sites More sharing options...
Chris_B-1B Posted February 20, 2021 Share Posted February 20, 2021 Chuck - I want to try X-22 as a gloss coat for decals but would like to first ask you what ratio tamiya lacquer thinner to X-22 do you use? I'm also assuming it will work over an acrylic paint job. Am learning a lot from your (and everyone here) builds so thank you for your patience in explaining how you're doing things.

Best, Chris Hi Chris! I can’t vouch for X-22 on acrylic finishes, but I bet they will work perfectly. I use about 1/3 Tamiya Lacquer thinner to 2/3 Tamiya Acrylic X-22, so I have no reason to believe this is risky at all. Happy to help! My first 3 models had silvered decals that you could park a car underneath, so I’ve learned a lot of modeling tricks the hard way from others here, so I try to give back the same way when I can.

Have you tried future thinned with lacquer thinner(leveling thinner for me) ?? Yes it can be thinned with lacquer thinner!!! Thinned 70/30 favour to thinner... I tried it on my f-86 with Light passes....just to cover the decals...In my case it did not cut the shine I wanted... But again I want it a slightly dull NMF!! As for AK Interactive Gauzy, it is nice, May be does not dull the metal finish But it is like you put a glass over the model... Did not like it... My humple opinion!

John Yes I have John, with so-so results. One thing is certain in my mind: ANY clear coat will knock down the Alclad high shine metallic look, because they all take the reflective surface to a higher level away from the Alclad. The key, I think, is that if you must use a clear coat, make sure that it's as thin as possible. That's why Tamiya Lacquer Clear LP-9 shows some promise, so I have some on order to give it a try.

Cheers, Chuck Thats why I used highly thinned future. Anyway, I am trully very intrigue about this lp9, I will be waiting for your test and results chuck540z3 and Derek B 2 Link to comment Share on other sites More sharing options...
