I painted mine, I sprayed it audi red and did the end caps and buttons gold.
I gave it 3 really wet coats and it came out fine. I didn't clear coat it as I wanted to be able to take it off easily if I got bored.
Give it a good scuff first before painting though. Some 240 wet and dry to get the most off then just tickle it with some 600 to smooth it up a bit.
Will see if I can find pics if mine when it was painted
