## Questions & Answers

**Q: Is this a good primer to paint fake wood paneling?  If not what would you use?**
A: I've used mine to paint laminate, didn't work that great. I used to work in the paint dept. at Lowes and we sold this stuff by Valspar, called Bonding Primer, it's in a blue can. It's amazing!!! I've used it a couple times and it works wonders. I actually just told one of my friends about it because they're painting one of their paneled rentals and are having a hard time finding something to stick to the slick surface. He used the Valspar bonging primer & it came out great.

**Q: can it be used over oil based paint?**
A: Yes, This is the best primer to get any type of paint to adhere to oil. I repainted my oil based kitchen cabinets by using this primer and then a water based

**Q: Applied first coat of this primer weeks ago. Now going back for a second coat. How long to wait before i begin with third coat of actual paint?**
A: I didn't wait that long. After 3 or 4 days I put on second coat and a week later I applied first coat of actual paint. But my timetable was set more by my schedule than the cure time. I'm pretty sure you can apply paint after three or four days. It's good stuff.

**Q: Does the smell of this product last long?  Does it seal pine knots that are bleeding through finish?**
A: So far I have used this product to seal an old weathered Adirondack chair that had been oiled long ago, and I have now painted. Also just coated an exterior window frame that had partially been painted with oil base and partially latex which I wanted to paint overall in latex. Both applications have been successful in providing a bonding coating for the new finishes. I have not noticed much odor, but my sense of smell is not as acute as it once was. I think the product would seal the pine knots, but try an inconspicuous area first to test. I am very happy with the product and will continue to use it in appropriate ways. Read the directions!  Good luck, it's a great product.
