How many of you use PSP9 for painting?

I do.. it's my favorite paint program. I also use Photoshop CS6 and Gimp when some of the larger templates will not open in PSP9.

I have used PSP8 since 2004

Yep, since 2007.

While I have never really painted a car file for NR2003, I do have to make billboards, wall graphics, etc. for our PST short tracks. I mostly use PSP7, but there are times I use PSP9 as it has a few more features and flexibility that PSP7 doesn't have.
