Topcoat Weirdness from Draw Decal + Tamiya Acrylic + Testor's Clear Flat


Recommended Posts

I'm looking for any insight into why this might have happened, if anyone has seen this before, or if anyone has suggestions on recovery options?

 

The short story is that when I applied the clear flat, the paint noticeably darkened only around the edges of the decals.

The long story is:

1/200 Hasegawa 737

Primed with Tamiya Gray Surface Primer

Fuselage airbrushed with Tamiya acrylic green

No gloss coat - green was pretty glossy to start with

Draw Decals 2nd generation Digital Silk decals per their instructions - warm water, no more than one or two applications of Micro-set/Micro-sol, and they looked pretty good. 

Sat on the shelf for a month or so...

Today I went out and topcoated with Testor's Clear Flat out of the spray bomb (my goal was to buff the fuselage to give it a satin look and keep the wings flat) and I got these super weird shadows around all of the decal edges, a tiny bit of dissolved paint and a boatload of wildly consistent ghosting/silvering.

 

I get the silvering and maybe the tiny spot of dissolved paint is likely my fault, but what is up with the shadows?  The green paint darkened only around edges of the decals, the rest of the acreage is fine. The areas around the "kulula fans" and "throne zone" text show it best.  It's almost like something in the flat pulled something out of the decal film and discolored everything.  

 

I don't like my "Spanish school" 737....any ideas??

 

TIA

Thanks, fixed the picture.  I'm fairly certain the decals don't require a clearcoat ahead of time, but they are printed on a continuous carrier and needed to be trimmed.  There is a LOT of clear carrier left because of the windows and text relations - hopefully it will make sense why now that the pictures are up....

I would wait a long time (a few weeks at least) and then try using other clears on top of that and see if that has an effect. It might be that the coating of the decals dis something to repel the Testors clear you used, and another kind of clear (like an acrylic clear) would even things out.

 

I've had Testors Dull Cote create random "silvering" when used on humid days - it wasn't traditional decal silvering, but moisture trapped in the clear. That worked it's way out in 6 months, and looked fine after that.

That's interesting about the Dull Cote clearing up- I'm in WA, and it (shockingly) had just stopped raining before I went outside to spray, so I'll definitely take that advice and see if it gets a little better with time....

There is your problem.  Always gloss coat the entire model after decaling to give it a uniform sheen and to protect the decals from the harsh flat top coat.

Well, spejic was right about things clearing up with time - the decals and paint now look almost the same, but I still can't figure out why paint would only have dissolved around the edges of the decals. 

 

You would think I would have issues all over the plane if the clear was too much for the paint.  My last build I used Tamiya acrylic, Tamiya decals, and the same can of clear flat with no issues....

Going forward I'll definitely take RichardL's advice to heart and remind myself to stop thinking I can get away with shortcuts!!

 

Thanks
