There are obviously some out there, because you can buy vinyl windows
painted on the outside, as well as painted on the inside, or painted
both sides, from some companies.
I believe Krylon makes a compatible producr. So does Plasticote.
Colours will be limitted.
Automotive finish with the "flexane" adittive used on urethane bumpers
should also work, but preparation is important and critical.

"Question: My house shutters are looking shabby and need repainted.
The shutters are made of vinyl and I want to be sure that whatever
paint I use will last. Which spray paint do you recommend?
Answer: We recommend that you use Krylon Fusion for Plasticฎ on your
exterior vinyl shutters. Fusion for Plastic bonds easily to hard,
rigid, non-flexing vinyl surfaces, such as vinyl shutters and
vinyl-clad windows. Its also easy to use because no sanding or
priming is required. Plus, it dries in 15 minutes or less."
I used Krylon Fusion on an inexpensive plastic patio set like this:
It took something like 6 - 8 cans to do 4 chairs and the 4' diameter
It looked pretty good for the first season, but then it started to
chip. I touched it all up with a few more cans but it started to flake
off after a few months.
Tip: don't try to knock a block of ice off the chair seat. Most of the
paint stuck to the ice, not the chair.
OK, I lied. I just got home and checked the product.
It was the Rust-Oleum Specialty Paint For Plastic, not the Krylon
Prep instructions were followed:
For age or weathered surfaces...clean with soap & water, rinse and let
dry. (The set was at least 2 years old, living on the deck the whole
Dry & Recoat instructions were followed:
Standard spray paint times...to touch in 20 - 30 minutes, to handle in
1 hour, fully dry in 24 hours. Second coat within 1 hour or after 48.
There is a note that says "Maximum paint adhesion and durability is
achieved in 5 -7 days." Nothing about not using it or keeping it
inside during this time period. In any case, as I said, the paint
lasted for a full summer season - not every day use by any means, and
not for anything other than reading the paper and having a snack on
It was during the spring clean-up that I noticed the paint was
chipping, except for the one chair where I knocked the ice off during
the winter and the paint came with it.
The can doesn't say it, but perhaps the painted surfaces are not meant
to be left out for the winter.
The lack of adhesion is likely due to Krylon misleading you into
insufficient preparation. Krylon's claim of "prep unneeded"
notwithstanding, nothing will stick very well to the layer of oxidized
plastic that covers the good plastic underneath, because the oxidation
itself doesn't stick.
