Solution of ABS in methyl ethyl ketone (MEK), a common solvent for PVC pipe work (drains, stormwater, agriculture) was discussed in these forums a while back. I have used ABS in MEK for repairs and installations in compact AIOs. The weak link in ABS is, I suspect, the butadiene component, which not only oxidizes more readily than the acrylate and styrene, but embrittles the copolymer as a result of its doing so. It may also be that an ABS-in-MEK cement will not have a long life for similar reasons, and therefore have to made afresh for each repair job.

The burden of all this is that acetone- and MEK-based 'paints' should have good adhesion to Beige ABS Mac cases. That cannot necessarily be taken to include Beige (or, rather Platinum) metal-clad Macs such as the 81, 85 and 9500.
