I snagged a paint pen from Michael's, and gave it a try. Started with the bottom of the bottom bracket, hoping to get the hang of it, and I did get better as I went along. Here are some observations, they might help a novice trying this for the first time.
- The angle is important, as is keeping the pen upright - best you can.
- A slow, light touch helps the paint flow evenly. At first I was pressing too hard.
- Expect to go over it twice, and even more if needed...especially where there is a gap.
- Have an alcohol q-tip ready for mistakes. Or, let them dry and scrape off later.
In my mind it looks decent. Not perfect, by any means, but it easily passes the 6' test.
I've still got some scraping to do, and some more spots to fill in.
