The silicone baffle material was perfect for the cowl seal on the Aeronca Champ.

The baffle material is thin enough to take the proper lengthwise curve to seal the baffles against the upper cowl. Some other products are too stiff and thick and leave gaps for cooling air to escape.

Repaired, primed, and painted baffling with epoxy white. Trimmed with blue silicone seal material. Looks great! The last silicone seal material lasted over 20 yrs. I expect this will last as long or longer.
