Do they sell the POR15 engine enamel in a rattle can also ?

Not the last time I looked.
 It is super thick if not thinned, but is tough lovely stuff that if cured is super resistant to abrasions and discoloration. I did an automotive engine  and other than scuffing the oil pan while installing because it was still a bit soft, I cleaned and painted the motor in a weekend in the cold of northeast Ohio during a winter weekend. I didn't have time to do extend that window for more curing time. Used a kerosene torpedo heater to help it cure for about 6-8 hours and it sat for Maybe 24 hours before being dropped in the car... We caught the oil pan on the cross member installing it as the manual transmission didn't want to rotate as we installed. The scrapes in the paint of the pan never spread and while the bare steel developed a light rust where it was scratched or scarred that rust did not spread underneath the paint. Any later oil leaks or spills could be washed off easily with soap and scrub brush without affecting the gloss and it stayed glossy.
Incredible paint...
It was not cheap stuff when I did it in the 90s and stripping the engine of oils prepping for paint was the hardest part. But the paint clung despite the block not being what I considered to be clean enough.  I brushed it on and it closed out and had no evidence of brush marks.

Here in UK we use Simoniz SIMVHT31D
The colour match is spot on and it's very hard wearing. We've painted hundreds of CB SOHC/4 engines with it (as have many forum members here in UK) with no issues reported.

Julie, I found the Simoniz lifted if fuel leaked onto it. When I repainted, I used Simoniz, then a light coat of clear engine lacquer. I'm only 1,000 miles in, but it seems to be working.

Hi Mark.
Never had that problem ourselves on our own bikes
but, if I dribble a bit of fuel on the cases accidentally, I just wipe it off quickly and it's OK. I have heard on Facebook of owners moaning that their carbs have been leaking for 6 weeks and the paint is coming off, well I'm not surprised it's coming off in the slightest to be honest, fix the bloody leak 🤣🤣🤣.

For all the Duplicolor users, or experts my base coat stuck nicely to the aluminum but my colour chips super easy, I followed the can, and Duplicolors instructions to the best of my abilities. I even used a heat lamp to cure… I can’t be the only one to find Duplicolor brittle. Also find it waaay less resistant to gas or brake clean. I powder coated most of the side covers but the cases I painted.

Once again. Rattle cans NEVER cure. Even with a great amount of heat and time. You need to use a catalyzed paint or 2 part Epoxy if you want it to be fuel/solvent resistant. Put a good 2k clear over the duplicolor and fuel will not affect it.

Likely Hondas paint was a type of epoxy because most of it looks great 50+ years later
