Spray paint for thermal detonator tube portion

Spray paint for thermal detonator tube portion!
 

I’m building my thermal detonator by wrapping the pluming tube with the electrical cord from Home Depot. I am curious to what brand and color spray paint people are using to paint it. There seems to be so many different gray colors available.  Gloss, satin, matte?
 

thanks!!!

I would use a satin or matte color in a "neutral gray" shade.

You can get a good sense of the color in this photo from the magic of the myth exhibit:

You can spray it and a number of people certainly have, but the solvents in most spray paints react strangely to rubber coatings like you have on wire cording -- sometimes they don't really ever dry, which leaves you with a slight stickiness that never goes away.

Now, full disclosure I haven't used this specific color in real life, but you might want to look at something like this, which is an acrylic spray paint in neutral gray: https://www.amazon.com/Liquitex-Professional-Spray-Paint-Neutral/dp/B008N7HCXK

In addition to what Chopper just said...

I recently just redid my wire for my TD, because I was unhappy with the medium gray color I used AND -- like Chopper said above, the solvent in the paint reacted with the rubber in the cord and was super tacky and left paint marks everywhere.  It was a mess.

I found a different paint that looked more along the lines of that 80s gray-beige telecommunications wire color (Rustoleum Satin Stone Gray).   So I applied it and... same issue.  Got real sticky and wouldn't settle on the wire.  Color was great though.  

So this time I took one additional step:  I clear coated it with a satin clear coat.   Stickiness is gone and the TD is totally workable now.  So don't forget the clear coat!

If you don’t want to go the paint route or it gives you issues, you could try gray electrical lamp cord, 16/2 should do the trick. You’d just need to split the cord in half down the middle, which is easy to do, so that you can wrap it around the TD tube.

You’d need to make sure that both wires are encased an a smooth casing. Sometimes one side is ribbed and the other is smooth. In which case you’d need double the length so that both sides of the TD could be finished with the smooth casing and look uniform.

Thanks everyone for the feedback.  Good to know and I will add this to the list!

You might also have success in coating it with plastidip and then paint. I've only used the Montana gold (acrylic) paint over it but it works great.
