Spraying Prints to Seal

Been a while since I picked your minds. A while back my wife bought me a H.P. Laser printer. I got the word about sealing the prints which I have been doing. I have been using Krylon sprays which I can buy at Michael's. My question is in your opinions what is the best spray to buy. Are there other types I should be using other then UV-Resistant Clear? Thank you. wc
