What Sealer to Use

Submitted to Product Chat

I'm a glutton for punishment. My American Legion post has a Golf Outing with Raffle/Silent Auctions next week Saturday, the 20th of August. I already got the donations for them that I usually obtain from businesses but wanted to do more from me on a personal level. Thus the 4"x24" wooden signs. I have two more to make but they go pretty quick. (So far Army, Marines and Air Force are done. Still need NAVY and Space Force)

My dilemma: I want to seal them lightly/quickly but I'm clueless on how to do that. They will be marked for indoor use only. I want to seal them to keep the vinyl in place.

Hit me up Creator's! What do/would you use? The easier the better, I'm running out of time, as usual!

P.S. As you can see I'm using Painters Touch Ultra Cover to paint the boards! No Priming Necessary! WOOT WOOT
