I've refoamed tons (well, not literal tons, of course) of woofers, mids, etc., but I don't recall ever doing a pair of the Infinity IMG cones so I thought I would ask this here. What's the best and safest "chemical" for removing the leftover foam and adhesive on some Infinity IMG cones? I've used MEK on frames in the past and on some thicker paper cone woofers...outdoors, of course. But, that stuff is quite strong and I'm not sure how it would react on them and I'd rather not eat the cones up. My Quantum 3's are Watkins paper cones and the RS-IIIb's are poly and they were fairly easy to work with. So what say ye Infinity fans? I've got 2 woofers and 4 passives (potentially) to do.
