After letting my 104 pilot sit for over a week waiting to de-gas, and considering using more oils, I went web searching for a faster drying method.
I'm late to the party, having only been modelling for the last two years after a 35 year hiatus. (so all of you probably know all about this) I've only been using oils the last six months as I strive to improve finishes and add more interest to my models. Every time I've used an oil wash or oil streaking I'd have to wait 1-2 weeks for the paints to de-gas.
I am not a patient man.
Two days ago, I read of a substance called Liquin. It can be painted on after painting with oils. I watched a YouTube video seeing it done. After further reading, I headed to my local art supply store to get a bottle after checking them out on the web to see if they carried it.
Alas, the spots on the shelf for Liquin were empty. Asking the clerk about how soon it would be restocked left my impatient self unhappy with further wait, but fortunately the clerk directed me to a product by the brand name Art Spectrum. (this is an Australian brand)
The product is called Liquol (No4 Medium)
So, on to an experiment:
The control group was three gray styrene surfaces airbrushed with white oil paint thinned with Turpenoid. (All surfaces had been marked with black Sharpie to ensure coverage)
The variable group was three gray styrene surfaces, again marked with black Sharpie to ensure coverage, with white oil paint thinned by the Liquol.
A word about temperatures: It is early winter here in Australia. Night temperatures are dipping down to around 55 degrees F (13 degrees C) and daytime highs around 70 degree F (21 degrees C). There is no furnace in my place, so paint drying temps are a little lower than optimum.
After 6 hours, the Control group was easily smeared by light touching.
After the same 6 hours the variable group was what I'll call very tacky. The kind that you think will lift off on your finger, but doesn't.
After 12 more hours the control group could still be marred by a firm touch.
After the same 12 more hours the variable group was only lightly tacky.
After 24 more hours the control group is easily removed to-the-plastic with a light scrape of the fingernail.
After the same 24 hours the variable group feels dry enough to sand. However, light scraping with a fingernail will leave marks on the top layer of paint without pulling the paint from the plastic.
