First of all, I have to state that not all proofs are found by me. Credits goes to CYBORG KHALIFAT, Kart-man and Gold in my dick, what up for some of the proofs which I extract from the previously closed suggestion 2 weeks ago. No one in outpost is selling this paint for 1 ref anymore (I'm not talking about buyers link). Majority of paints at 1.33 get sold pretty well.

The last suggestion had a huge argument going on there, which is also how I get all my proofs :3. I would like to stress that it is indeed possible to sell at 1.66 ref. Taking Kart-man's trade for example (as his is quite recent). Only 14 views and already 1 add just after 2 hours of posting it up.
