I wouldn't be to worried about the lettering on your hat and your blazers busting you. Remember that things in nature do the same thing in giving off UV. So small objects won't stand out like a sore thumb. Now your clothes and such will as they are such large solid objects giving off the UV.

Iwill try this also and see just how bad my gear glows. Got a nice UV light packed away somewhere in the closet. All of my clothes are washed in scent and UV killer, except my new leafy suit which is only washed in scent killer. I ran out of my normal washing stuff and haven't made it to the store for me.
