I finally got around to resealing my AR-3a. Got what I assume is mortite from the AR guy on ebay. Well, the woofer is still leaking. I held my face really close to the cone while pushing in and could feel the slightest amount of air movement on my cheek. I think it's coming from the foam surround - got the foam from the AR guy too. I don't think it's from the dust cap. I checked the seal on both sides of the foam and it looks very tight.
I thought I'd do the permatex treatment to the foams at a really diluted rate but wanted to check with you guys first. Here's a pic of the woofer:
