help, need rhino liner application advice

Trying to paint on SEM 40674 tintable Pro-Tex truck bedliner with the 40661 activator, using the 3m gun and the product is coming out reall spitty, like i'm trying to apply drywall mud through a straw. I mixed the parts correctly (8:1) and am using 60 psi at the gun.

Looks like poop

am i missing something?

al;most seems like i need to ad a reducer but it does not call for anything

help

thanks

andy

Sorry, my mistake in the original post, i did actually mix the product 2 parts material to 1 part activator as outlined in the directions....(the 8:1 was for the tinting
