It cost some to do it home, strip all paint and 2k bondo. Find new dents to fill, sand, fill, sand, fill and sand again. 2K primer, sand it again. Base coat layers until even color let it cure a few minutes between each. 2K clear 30 minutes after last layer of base.
Wait one week, sand it and add graphics. Wait a week more and 2K clear on tank again.
The garage smelled like shortened my life a few years, the paint stripper reduced some too
My idea was to make it cheap, I did not count all hours hard stinking work. All material needed costed some too.
Leave it to a professional is not expensive was my daily thought when doing this one year ago. My result look OK from 2-3 meters a sunny day.
I'm sure a pro like Menno does it perfectly, better than Honda did. I have read several happy customers threads on the UK SOHC site.
Edit
Sh!t, threads like this give me ideas $$$
My K6 bike had an almost turquoise blue from the very beginning. The Candy Sapphire Blue tank of old style Yamiya sell and bike has now is darker.
My K6 might need to get a K6 tank with correct petcock and correct color.
I must find a K6 tank without dents, my original has dents and rust. I might PM Menno another day.
