Wash stain with oils on acrylic

I did my first oil wash on a clear gloss acrylic.

Prior to this I tended to use pastel washes and other acrylic washes, with varying results. I still quite like pastel washes, they just have their limitations.

I was quite surprised how the oil brought out very fine panel lines and I quite impressed. The capillary action was very good. I think for fine panel work, I have not seen a technique work as good as this.

The problem with one item I did with the oil wash (tube oil paint + odorless varsol) was that on one subject, it lightly 'stained' the acrylic gloss underneath, and no amount of cotton swabbing with more varsol is removing it. I have a feeling that I did not let the acrylic gloss coat dry enough... I put the oil wash over it about 4 hours after the gloss coat went on. Would that be the only issue?

Note that the acrylic gloss I used was from a spraybomb. Is Future better for this sort of wash than an acrylic gloss?

Ah, went for the quick dry method.

Try a bit of odorless turpenoid.

Future would probably be better for a short timeline, I think.

Oils are nice, as are watercolors - particularly the transparent ones.

I'm impatient, so I use naptha thinned oils over future for my washes. Naptha dries in minutes, leaving a nice layer of oils. It tends to weaken and even crack bare plastic, though, so a good coverage with future is essential. I put down at least 4 layers of future before washing; I've screwed up too many finishes not doing so!

Sounds like you went too fast. I feel yer pain. I like to paint fast and furious, too! Just have to force yourself to slow down. I've been doing it lately and it's really paying off.

Those qualudes helped eh?

That's why I really like the watercolors, you can remove excess as soon as the water carrier evaporates. And if it's not good, a damp swab removes it and you can do it over. Takes way less time. While oils are a little more durable, I usually seal them as well anyway.

Oils are a bit more subtle, though, and have their own uses beyond just washes.

Next questions guys, sorry I don't use oils so Im asking some probably obvious questions. Can I put a clear acrylic back over my oil wash. Note the oil wash was done over an acrylic clear. I've let it dry for a few days now...

Sure thing. I clear coat all my oils, other wise they never sop being messy.

Kylwell, you've always got great advice, thanks so much! Now I have to get back to work. Doing a swimsuit calendar at the moment, life's tough...
