3M Paint Defender Success Story
Readers of this thread know that I previously used the 3M spray unsuccessfully. I gave it a second try. What a difference some practice makes. As you'll see towards the bottom of this entry, the 3M delivered good results.
STEP 1: PREP & WAX
I covered parts of the bike using saran wrap and painter's tape, leaving the parts that would accept the film exposed. I then applied the supplied 3M Synthetic Wax Protectant. It's supposed to keep the surface slick, which will help you remove the film someday. FYI, that wax is good stuff. I may use it on a permanent basis for my bike tank.

STEP 2: SPRAY
Next step is to spray. Instructions for spray are found here:

Learn from my mistakes by erring on the side of excess. My first attempt failed because I was too light on the spray. This is a picture of my first attempt immediately after spraying. The film dried into a similar, and very thin, pebbly texture.

I removed the film from my first attempt and tried again. This is my second attempt. See the difference? The second time the spray is much thicker. You can see a lot of white, which was missing from the first attempt. That's the sign you are applying the correct amount of spray. If you don't see white, it's not right. Note: I applied the film in three segments - the right panel, center and then left panel. Each segment received the 3 passes of spray required by the 3M video instructions.

STEP 3: REMOVE PAINTER TAPE
About two or three minutes after applying the spray, I removed the painter tape from the bike. This is intended to keep a clear break between the tank and sprayed areas. If I kept the tape on while drying, part of the film may settle on the tape. There might be some puckering on the edges of the film, if you remove the tape then.

STEP 5: LET DRY
I left my bike alone for the night. The next morning, this was the result:

Can you see the demarcation between the 3M film and unsprayed areas of the tank? From a few feet away, I couldn't. Instead, the film-covered areas look like original paint. It's only close-up (as in a foot or two away) that you can see slight imperfections, such as the occasional dust mote that settled on the film before it dried, or water-like ripples.
The film texture is a bit "grippy," and not smooth like paint. I read elsewhere that applying wax on the sprayed areas will make it smoother, but I haven't had the chance to do so. I will do so next Saturday after the film cures.
STEP 6: CONCLUSION
I'll update this thread in a few months, after I get real-world evidence about the film's longevity and durability. For now, I'm pleased with the results. The film looks good, and it should protect against the minor scuffs that appear on the tank, as a result of your riding pants rubbing on the tank's sides. I like it.
Hope this proves helpful.
APPENDIX - Tip if your first attempt fails, and you need to remove the improperly applied film
Please note that if you apply the spray too thinly, you may have trouble removing the ensuing film. Because it is thin, the film will come out in patchy chunks instead of a single, continuous piece as seen in the 3M videos. For example, I removed a quarter-sized spot of patchy film after 15 minutes. I then got smart and called 3M for help. The customer service rep advised me to use 3M glass cleaner as a solvent. It worked: spray on the solvent, let it soak a bit and use a soft microfiber rag to vigorously rub away the patchy film. 3M said ammonia-based cleaner would also work, but I subjectively got better results using the 3M product. I suggest rewaxing your tank immediately after that, or the glass cleaner may harm the paint.
