I've used them too. Nice opaque white. Not the ability to play around with dry transfers like decals, so AMCDave, that's a very good idea - I like it.

It's gettting to a point where there's scant little choice in 0 scale either in dry transfers or decals. I like the 0 scale generic data sets produced by Rail Graphics. I could mix and match larger HO scale decal logos and hearlds with 0 scale data on traditionally sized cars. But now Rail Graphics has DISCONTINUED them in 0 scale.
This is a real loss, along with the many many sets long ago dropped by Microscale with scheduled to be discontinued in 0 scale, not that there are all that many left in production.
I've talked to a couple distributors of Microscale seeking some decal sets. They tell me they've been getting more frequent requests for 0 scale decals. This is one instance where requests might bring some decal sets back into production. I was told by Microscale the reason 0 scale decals have been dropped is that they DO NOT SELL. If they'd been selling, they wouldn't have been dropped.
Anyone here know the status of Oddballs Decals. The website hasn't been updated since 2011, and there have been many posts here in the recent past about their delays and otherwise poor service.
I've posted these before, but just for continued info, here's a couple remaining 0 scale decal makers:
