Sometimes, all you have to do is 1) ask the Paint Retailer, and 2) ask the Wallpaper Retailer. IT would be much quicker than waiting for an answer here.
Anyway, I have some help for you. Try, Painting Paneling I, or Painting Paneling II, or Painting Paneling III.
As for the border question, re-read the directions that apply to the SURFACE to which you're bordering. If you have questions on the installation, w/o seeing myself, I have to refer you to the Retailer or the Mfgr. My best to ya and hope this helps.
