I have enjoyed this site and made use of a lot of the how-to information. It is invaluable. So, I documented what I did in the hopes someone else might enjoy this. It is my own way of paying back the community.
So, I have this really nice 1997 GL1500SE (and a not-so-nice-yet 1982 GL1100A). As pretty as I can polish it up, there was always something missing- the lettering around the ignition switch. To some this may sound silly, but it always bothered me.
A long time ago, in a galaxy far far away, I had a custom bowling ball made for me, engraved with my name. I remember the bowling pro fill the engraved lettering with a special sort of lacquer crayon. I started researching and found out it is called a "Engravocolor Stick". Trying to find these on the internet was really difficult- down right virtually impossible. I can find the company name, and lots of BS sites that just use their own invoice and page back to the company's ordering web site. We can talk more about that little scheme later. However, I could not find pricing at all. Being a weekend, calling the company didn't work either since they were closed. This was really irritating me. I finally found a snippet of a forum conversation where someone mentioned there were about $8-10 apiece.
I started pondering. My MacGuyver instincts took over and I tried a few different methods to accomplish this amazing feat. After a bit of experimentation, I zeroed in on a plain old wax crayon.
First, clean the area to be filled- I used a toothbrush. Then, take a plain old wax crayon- the whitest one you can find, and just start rubbing it in to the lettering. Go around in circles, horizontal, vertical, whatever. The object is to get the wax heavily into every crevice and corner. Don't worry, you cannot put too much.
Take caution not to get it into areas you don't want filled. It is easy enough to clean off (especially when Pledge is used on the bike), but why go through the hassle. You might even want to pull the plastic off from around the ignition switch. I thought of that after I did the job...

Next, you want to take a shop rag and lightly rub off the excess. If you use too much pressure, or a rag with extra fluff to it, you may pull the wax out of the lettering. Then you basically want to buff the area until it is nice and shiny. I used a red crayon for "ON".
Don't worry, you can touch it. I even lightly used Pledge right over it, but I wouldn't do that too heavily since Pledge cuts into wax. I used Pledge and a toothbrush to get all the old paste wax from the previous owner out of between the lettering on the light lenses, the various badges around the bike, and all the seams or fit around the plastics and it works real well.
Then, I saw the Honda logo staring at me, needing, pleading for some attention. So, since the logo is red... And, so I see the maximum number of attachments to this post is 8, I will continue in a reply.
