The O-320 baffle instructions says to use Pliobond to glue the baffle seal strip to a backing piece. Here’s what I found out:
Using McFarlane’s Cowl-Saver baffle seal, on the slick black side, Pilobond didn’t work at all. It readily peeled off. I called their tech support and was told that nothing would stick to the black side’s Teflon surface. This is the side which needed to be glued, so I could not glue to the gray side.
Using Van’s baffle seal material, I tried Pliobond. It didn’t stick well at all.
I’d previously determined that red silicone baffle seal would not stick with Pliobond. For that, I'd successfully used Ultra Blue silicone.
I made a test piece of Van’s baffle seal material and some scrap aluminum and tried Ultra Blue. It did not stick, just as McFarlane's support had predicted..
With another test piece of Van’s seal, I opened some Pro-Seal that I had stored in my freezer since new and tried it, too, once it warmed up. This sample did stick, with poor -but some - peel strength.
And using a final test piece, I tried Pro-Seal and the black side of McFarlane’s Cowl-Saver, just on the off-chance that it might work. As McFarland’s support had predicted, it didn’t stick.
Having ran out of glue options, I'm using a rivet.
