Hi Peter.
1. Yes, Raptor nails can take primer, paint, and even stain. We also produce nails in different colors, however we do not color match. We recommend customers request a sample in order to view the coloring.
2. It depends on the thickness of the wood, as well as the dryness. If it’s 3/8″ thick or less, we should have a solution. If it’s a little thicker, we may still have a solution. It just depends on those factors. We are happy to discuss here or if you wanted to contact us directly at info@raptornails.com or 512-846-4027.
