Sparmax TC-2000 Compressor at Hobby Lobby

There is no perfect formula for thinning Tamiya paints. But the consensus is to thin to the consistency of 2% milk. If you are going to go the Isopropyl Alcohol route, try to find a purer mix than 70%. The other 30% is a melange of additives and changes from brand to brand and even batch to batch. Pickup some acrylic retarder as well, or you'll be visited by the tip dry fairies. I prefer using Tamiya's own thinner in the 250ml bottles. It comes with the retarder already added and isn't that expensive. I've never figured out why people insist on cheaping out on thinners for expensive paint!

Picked mine up today, they've got the 40% off coupon going right now.  Funny thing, the lady wouldn't let me carry it up to the register, had to carry it herself.  I made a joke about stuffing it down my pants and apparently someone almost pulled off that exact stunt by pulling it all out of the box and stuffing it down their pants...?

I picked up some Tamiya paints, what ratio should I dilute them to for airbrushing?  The people at the store mentioned using 70% alcohol to thin the paints...?  Is this something unique to Tamiya or just a general practice, I'd assumed that you always used water to thin paints for airbrushing.  Why would you use alcohol, and would you want 70% ethyl alcohol or 70% isopropyl?
