Canon touch up paint

If this has been covered in another thread please let me know.
I'm wondering if anyone has found an over the counter spray paint that is a good match for my 100-400 IS ii lens? I want to paint the lens hood as I'm not fond of the factory black.
I have one from Vello that matches my 70-200 IS ii color but they don't offer one for the 100-400. Also would be interested in touch up paint in a bottle if anyone knows of any available.
Any help would be appreciated.

I found matching paint on eBay. It’s been a while but I’m sure it’s still available.

From what I understand, Humbrol 28 matches Canon white. I bought a can but I haven't used it yet. Cap color looks right.

If you buy it this way, the can is 14ml - tiny. I think Humbrol makes model airplane paint, so think that quantity and the brushes you'd use to apply it. It's touchup paint. Don't know how many cans it would take to cover a whole lens hood. Don't know if they sell it in any other volume.
