Hey guys, bought a lensboard for a C1 from an ebay seller, had to sand it to fit. This resulted in some of the black stain coming off, what would be a safe combo of black stain and varnish to use on it?

I'm presuming I need something without too many volatiles,

types not brands would be great as I'm in Ireland and prob wouldn't be able to get eact matches, thanks, D

Any quality outdoor synthetic enamel will work, I guess (heat and UV resistant, like those used on metal fences, windows, cars, etc).

Actually, I have my homemade lens boards (and other parts) painted with Humbrol enamel for model crafts (black matte); they smells forever, and I don`t find it to be specially good.
The black matte finish is still a bit reflective, definitely not as non reflective as the original camera parts, but it works. Maybe, the advantage of using this paint is because it`s relatively thin, while non-hobby synthetic enamels look thicker (denser). But you can dilute any of them up to limit (I actually use the Humbrol diluted a bit). The abrasion resistance is low, just use it a couple times and will start to wear, and the matte finish is easy to mark, e.g., with a nail.

What I`m not sure is about the UV and heat resistance of these. In summer, all that painted things smell; so I always think next time I`ll try with a non-hobby quality synthetic enamel (the ones sold in hardware stores). I have painted windows and fences with with them, and looks to be much better.

Anyway, I don`t overthink this things too much. I use to take the can I have at hand.

I use cellulose car paints, mainly because they dry quickly.
I'm probably using totally the wrong stuff but at one time I had a few red boards to match the B&J's red bellows, I need to see somebody.

I use 50mm wide permanent markers for any blackening. Cheap, fast, covers well and is non-reflective. It applies as ink and has nearly no thickness. Touch up is easy. I have covered vast areas of ULF and smaller with these great markers. There are meant for art and signage. Is graffiti art?

I use this one, when I can find it. http://www.amazon.com/Kuretake-Posterman-BIGGIE-50MM-Marker/dp/B0094L3JAE/ref=sr_1_4?ie=UTF8&qid=1398356771&sr=8-4&keywords=50mm+marker

Anything that isn't lead based. That is for your safety and not the camera's or the lens. It really makes no difference once it is dry.

I just use latex enamel flat black paint. I purchased it at my local hardware store, Lowe's, here in Southern California. It is their line of paints, Valspar indoor/exterior paint. It is made for wood, metal and more.

I'm sure you can find something similar in Ireland.

India ink, followed by shellac and steel wool in line with the grain the next day, after it's dry, looks real nice, and is totally safe.

Best flat black paint is Testors Flat black spray. http://www.testors.com/products/573133

Better than that is black flocking paper. It's like a black hole. http://www.edmundoptics.com/lab-production/general-tools/light-absorbing-black-out-material/1502
