I just bought a FT it has a diamond plate IF. Around each of the 4 fish on the lower IF-- if I can describe this right. There is a square box that is not level with the IF--My question is where do I order a mylar cover for FT and are there any videos that show the proper procedure to install mylar also will it make any difference if I install it the way the 4 fish are on the IF??? Some of these questions might be stupid please be patient I am new to the hobby and have never attempted anything like this before. Thanks, Henry
