Vinyl siding has positive and negative aspects. On the positive side, it looks pretty good and can cover some nasty flaws in the old siding. On the negative, it is very difficult to change the color when you get sick of it. Not every paint works on the stuff.
Here is one that does and can be tinted with any color you like.
As you can see this siding has been painted out from blue to white or rather fresh cotton. I have used Sherwin Williams® Super paint exterior acrylic latex. This project needed two coats but it looks fresh and new.
Enjoy and happy painting!
