I'm going to post these over in the Model Railroading section of the forum but wanted to share them here as well.
Last year I sent an Atlas RS3, a Walthers caboose, and a Proto GP9 out for custom painting and just got them back today. I'm pretty thrilled with the results...
All three were painted and customized by Accurate Custom Finishing
http://www.accuratecustomfinishing.com/.
654 was a cheapo Walthers caboose in Guilford paint that was stripped down, repainted, and provided with new couplers.
9935 was an undecorated Atlas unit that was kitbashed to represent it's DeWitt Geep conversion modifications.
7324 was a Proto Rock Island unit that was stripped, repainted, and provided with new drive gears.
The GP35 and 529 are production Athearn and Atlas units, respectively, and are shown just for comparison purposes.
This is my second time sending trains out to Mr. Tyrrel and I couldn't be happier.
