I've read through a ton of comments about sealing the lid on the RT-700 but, I am ready to purchase a RT-590 and interested in hearing from those who have sealed their 590 lid. Are you still able to achieve high temps? What size tape do you recommend? Are there tricks to applying it since the lid has angles, (unlike the RT-700)? The reasons I am thinking about sealing the lid are for added smoke flavor, efficiency and keeping it clean. I greatly appreciate all shared experiences and feedback.
