Sealing and Finishing (dullcote, glosscote, etc)

Postby michelalano » Thu Feb 09, 2017 9:24 pm

I'm looking for a list of operations for finishing models. I'd like my models to have as much longevity as possible in preserving decals, paint, anti yellowing, etc. I understand that common practice is a coat of gloss (for ease of decal application) and then a finish of dullcote. But are there any steps in between? I've noticed that on some of my past models, decals can flake off even after the dullcote. This leads me to believe that dullcote is not a "sealer" but merely a texture. I'd also worry that too many coats of clear could have the models come out gummy or lose crispness of scale, especially in 2500.

So in short, after applying decals, what method is best to "seal" and truly finish a model for maximum preservation?

I did a light search in the forum and didn't really find anything so forgive me if this has been covered. Feel free to point me to an existing thread if there is one.

What has worked for me:

After applying your finished colors wait a few days for the paint to fully cure then seal with a gloss coat. Then apply your decals. Then seal with another coat of the same gloss coat. This will seal your decals. Then spray with a clear matte/dull coat. One coat will give you a semi-gloss finish, more coats will give you a flatter finish.

Pretty much the same to me- but I also occasionally add in a coat of brush applied clear coat paint on top of the decal once it's where I want it - and if I'm going to be doing something other than decaling for awhile. The clear coat paint helps insure that it prevents it from peeling up.

Good idea. And sometimes if the decal has been torn a little while positioning it I will brush it with some liquid decal film before sealing with a clearcoat.

Thanks, great info from both of you. Is there a difference between "clear coat paint" and "glosscote"? Also I am getting some microscale decal film that I read in another thread to be painted directly onto the decal sheet to prevent cracking when applying.

Glosscote is Testors brand name for their clear lacquer gloss coat. Dullcote is the brand name for their clear lacquer flat coat. So clear coat is a generic term for either glossy or flat clear coats in either acrylic, enamel, lacquer, or acrylic/lacquer or whatever formulation they dream up next.
