The letters are machined (relief) into ABS plastic. They are 0.020" deep, and the grooves that form them are about 0.025" wide. The letters themselves are about 1/8" wide each.

I was hoping I could find a paint that I could inject into the letter using a syringe and a needle that is smaller than the groove width. But this requires a paint with low surface tension so it will fill up the letter instead of just forming a blob and not dispersing.

Attached is a picture of the letters. I have attempted to inject water based acrylic latex into them but it doesnt disperse well so it overflows.

Also the paint needs to be long lasting, UV resistant, and generally high quality because it will need to look good for years installed in an automobile cabin.

thanks for any help!

You will also need to buy some thinners like white spirit both the thin the paint & wash your equipment.
Good luck. ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/571361/6398147.page http://www.dakkadakka.com/dakkaforum/posts/preList/571361/6398147.page GMT
Never used them, myself, nor do I remember the brand to look up product specs, so I couldn't say if they'd be cost-effective and sufficiently resilient. I would think they're an option worth researching, at least, as it saves you the time and trouble of thinning and cleaning syringes. If they don't pan out or are too troublesome to find, bubber's suggestion sounds best.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/571361/6401022.page http://www.dakkadakka.com/dakkaforum/posts/preList/571361/6401022.page GMT imo.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/571361/6401243.page http://www.dakkadakka.com/dakkaforum/posts/preList/571361/6401243.page GMT
