Oops - Sign I have had some decals flake after years of sitting and also some lifting. Very discouraging to say the least. But I find the ones that had some clear coat are doing fine.

You mentioned you were using Tamiya TS (spray) paints. 

If you are going to seal the decals in Future prior to clear coating, Do Not clear coat with Tamiya TS-13 Clear or other lacquers.  The decals will crack under the clear within a few months.  It will look fine until then, but the damage/effect will be permanent and cannot be sanded/polished out.  

Enamels seem to work OK over Future, and urethanes are safe too.  Acylics are fine since Future is an acrylic. They stay a little softer when dry. 

The lacquer cures harder than the Future and with even minor temperature changes the difference in the expansion/contration rates will produce unwanted fissures.

 On the interior there are some small decals but the paint is not real smooth and looks kind of bumpy. 

If the paint is not smooth, you run the risk of the decals "silvering"

If the surface is uneven, has compound curves, or surface features over which the decal is to be applied, I highly recommend using a decal solvent. The solvent will soften the decal, allowing it to conform to surface irregularities. Once the decal is applied, brush a couple coats of decal solvent over the decal. You may have to work the decal into the grooves, bumps or whatever with your brush. Be somewhat gentle though, as the decal will be softer than usual. The decal may wrinkle a bit but that's ok, it will smooth out when it dries, but it will also be very soft at this time so beware.

Decal solvents are available from several sources. I use Microscale brand which is called Microsol. Other hobby product companies also make a decal solvent.

Microscale also make a product called Microset which is a decal setting solution, to be applied to the surface before the decal is applied, though I still question it's effectivness and rarely use it.

Perfection is achieved not when there is nothing more to add, but when there is nothing left to take away.

That's probably the best suggestion I've heard!! Gonna have to give it a try- thanks for sharing

Whenever I spray clear over decals, I brush a coat of Future Floor Polish over just the decals to seal them. Allow it to dry for a day before clearing over them. Also, do a couple of light coats first and allow it to dry. If it has orange peel, lightly sand it with 2000 grit and then spray a good wet coat.

Always apply decals to a gloss surface. If a flat surface needs decals, gloss coat the area first, then apply the decal. After the decal is dry, you can apply clear flat over the area.

As for spraying clear over the decals, that is up to you. It would not be prototypical, but I do it to seal the decal to the model. I've had decals flake off old models in the past.

Thanks. The rest of it came out better than expected, sure would hate to wreck the outside. One I figure out how to attach a pick I'll post some up.

No prob with yr ideajust make sure you leave the decals at least 24 hrs to dry before you clear over them.

Water slide decal question
Posted by Guts1882 on Friday, November 23, 2018 4:58 PM

I am almost done with my first build in 40 years and have a question on decals.

I used Tamiya spray cans on the body and some interior parts. On the interior there are some small decals but the paint is not real smooth and looks kind of bumpy. I want the exterior to look really good and was thinking of placing them on top of a clear coat then applying another coat when done with decals.

Is this a good or bad idea?
