"oregonpapa, Which is best to apply: NPS 1260 or Total Contact Enhancer? Which is easy to apply and a good price for the improvement? Thank you."
I have no experience with the NPS 1260. I do have extensive experience with Total Contact though. Sorry to say, it is no longer being produced. At this point, your best bet would be to go with the NPS 1260. It is getting good reviews from other members here.
