I was attempting to apply an oil wash to my latest project, and it
reacted with the paint, removing it where the wash was applied.
Here are the details.....
I used Model Master Olive Drab on the vehicle. After drying thoroughly I
began to apply the oil wash. I was using Grumbacher Lamp black oil
paint. In the past I mixed it with Grumbacher Oderless Thinner, but last
time I went to buy some they were out so I got Grumbacher Grumtine
All my past washes didn't have this problem, so is it the Grumtine?
If I still cannot find the Oderless Thinner, can someone recommend an
(If so, please give me some names to look for. I'd rather not take any
I'm not so far into this that I cannot fix the problem. In fact, in the
end it will probably be a minor issue, but I must have a proper wash
going forward. I use it too much.
Thanks for your input.
We're living in a world that's been pulled over our eyes to blind us
from the truth. Where are you, white rabbit?
You cannot apply an oil wash over enamels The thinner in the oil paint will
dissolve the enamel in a heartbeat. But I guess you already discovered
You must overspray the painted model with either acrylic or lacquer clear
coat prior to the application of a wash. A gloss clear coat seems to work
best for me. After you are satisfied with the wash, another clear coat of
gloss or flat to seal and blend the finished wash with the underlying paint
should finish off the project.
One advantage to using lacquer seal coat is if you don't like the way the
wash is going you can use mineral spirits to remove the wash without harming
the underlying paint.
Hope this is of some help.
Grumtine, though popular in the "paintin' on canvas" world, is pretty
much useless in model building, in my opinion. It is way too strong and
harsh (and stinky, and gummy, and overpriced, etc). The best thinner
to use for oil paints, is plain old mineral spirits. The cheaper...the
better. Get the type you find at WalMart for 99 cents a gallon; the one
where the label says "Paint Thinner". I am serious. This is perfect.
This will thin the oils with no problem, but won't affect the underlying
paint. You can even use it over an enamel undercoat, with no problem.
Just make sure the undercoat has set for a few days. And don't just
"slop" the wash on the model. Apply it as a controlled wash. That
way you run less chance of damaging the underlying colors.
Wait a minute! it's 99¢ at WallyWorld, $2.00 a gallon cheaper would mean that
they pay YOU a buck to take it.
Where IS this place, I can use about a hundred gallons! 8-D
