Oil weathering - is Dullcote enough to protect acrylic
Posted by ManCityFan on Sunday, July 16, 2017 7:55 AM

I plan to use oil paints on a T-34 I am starting.  On my last tank, I only clear gloss coated where the decals went, then used Testor's Dullcote in the rattle can over the whole model.  I did not use oils on that tank.

Will this be enough to protect the acrylic paint underneath, or should I gloss coat the entire model before Dullcote?  I use odorless mineral spirits (Mona Lisa) to thin the oils.

Thanks,

D

You don't need anything to protect Acrylic paints from oil washes.

Well, that is good to know.  One less thing to worry about.

Thanks Bish,

I sort of disagree. While you don't need it, having a clear finish allows idiots like me to wipe off poor applications and try again.

But if I go rubbing at wash over a base coat, I'll lose the base coat too.

It's always a good idea to experiment on a crap model. I have a few of those around. My usual method is to use turpenoid based washes over an acrylic clear coat.

That is a good point.  I have a tendency to "mess things up", and will undoubtedly have to rub off some of the wash.  No harm in adding the gloss coat, just an extra step.

Also without a clearcoat the oils may stain the paint and not wash down properly.

A gloss coat allows the washes to flow more easily. But it will not allow for any "dot filters" as those alter the base color best over a flat coat.

I have found that using a weak thinner like Mona Lisa will not take off even an enamel base coat. While some pigment may show up on the rag when you wipe off the wash, it is minimal.
