Clear Shield on UV prints

Hi, I'm doing a test of Clear Shield Select (the new version of Clear Shield) on UV prints on aluminum. Question is about application - tried 2 different paint rollers: the foam one produced a lot of pinpoint bubbles and a nap one less but still some (did not shake it but stir it). Would like to know what type of roller / mode of application you may have used with good results.
Also, anyone used it with UV inks outdoors (of course, I realize that they are not all the same)?
Thank you!

 

Thank you, will try that.
By the way, have you figured how long your prints may last outdoors?

 

Good to know, what we are testing is Semi Gloss, and I like the overall look except for the bubbles, which hope to improve on.
