I'm piecing together my baffling system on my ECI O360 on a 6A, using van's kit, but cannot find anywhere the dimensions for the seal material. The gap is to be 3/8" to 1/2" between the baffling and the cowl and sealed by the material. What is the nominal width of the material, and how much is overlapping the aluminum and how much is left to flex and seal on the cowl? My guess is it looks to be about 1" overlap on the baffling and maybe 1 1/2" to reach the cowl and seal, giving a total of about 2 1/2" width. This is purely a guess and I'm curious to see if there is any consistency between builders. How about it? Do you know what width you used?
