I did a small test on some left over Cofair Peal & Stick Aluminum tape. This is equivalent to Eternabond. I got it free, so the price was hard to beat. The attached picture shows where I applied Geocel Proflex RV flexible sealant (caulk) on the left side of the picture. On the right side I applied the sealant, let it set up and then brushed on the Geocel Proflex RV multi-purpose brushable repair coating. Both adhered very well, did not peal off and proved to be very flexible. I could bend and twist my sample and there were no cracks nor pulling away from the aluminum. They both worked as advertised. This picture is best viewed with Microsoft Paint in order to read what is in the arrows.
