Stupid question(s) for the week. I purchased the merlin hole protector from pinbits. It says it is compatible with the mantis hole protector. I've read about issues installing the mantis so I was going to hold off on doing that. Is there any requirement that the mantis be installed first or can you install it at a later time? Second question, I was surprised to see a piece of mylar the same shape as the protector. Is that typical for these types of protectors? I assume installation is simply remove the one post, put down the mylar, put the protector on top of the mylar positioned such that the post screw goes through the hole in the protector, replace the post and viola. Am I missing a step? Finally, I got the mylar protection pack at the same time. Lots of pieces of mylar in it. What are the top recommended spots to put it down?
