Hello All,

I am using very thin layers of Winsor & Newton oil paints on my tanks. Thus far I've let the thin layers dry for over a month. Does anyone know whether it's safe to use Model Master Lusterless Lacquer Overcoat 1960 over the oils? The rest of the model is painted in Model Master acrylics.

Thanks!

Some members have been having issues with these 2 products produced by the same company.
I have contacted them and this is their response regarding TESTORS DULLCOAT and MM LUSTERLESS FLAT.

So depending what paints you use, use these products accordingly.

Response from TESTORS

Thank you for contacting Rust-Oleum Product Support.

No the Testors Dullcote and Model Master Lusterless Flat are not the same.

The Dullcote is specially formulated to be able to go over any Testor acrylic, enamel or lacquer.

The Model Master can only be applied over enamel and lacquer in the Testor or Model Master lines.

If you have any additional questions or concerns please do not hesitate to contact us.

Sounds like you may be taking one for the team, KruppCake.

The sad thing about this entire coat business is that I am still confused about what exactly should be done with each product. For over ten years I have been using model master dull coats as a final sealant for models and have only had a problem once when I over-did it with one thick coat. In that case the only negative effect was a white buildup.

Each model is done with either tamiya or model master acrylics, and so far I have observed zero problems with this. However, I have not yet tried the same spray on oils.

Looks like it's time for DIY experimentation.

1.) Replicate your oil paint finish on a scrap model or empty beer can or whatever. Let the oils dry for a day. Try the matte clear coats on top of your oils. Observe the result.

2.) See what Windsor and Newton says. http://www.winsornewton.com/na/home/contact-us

3.) Visit your local art supply store and ask them to suggest an oil paint varnish since oil paintings are varnished to protect them from handling, dust, and etc.

Kruppcake,

You must use Dullcote as it is designed for any paint type.

Model Master Lusterless Lacquer Overcoat 1960 will damage
acrylics.

Cheers,

You shouldn't have any problems as long as you don't put on a thick/heavy coat over the model.

I agree. I have used both the Lusterless Flat and Dullcoat over all varieties of basecoat paints without any issues. They should be fine.

I suggest you do a test first. In my experience, lacquer thinner will strip oil paints. If you need to flat coat an oil finish, it should be done with an acrylic flat coat, which is inert to the oils.
