Foam Compatable CA is, as you say, just that it is CyanoAcrylate (supper glue) which won't decompose the polymers. IE: it doesn't melt (weld) the bonding area. CA bonds by filling the voids, not by making a weld. It is also shock and vibration sensitive. We used to replicate the old 'Super Glue' commercial by bonding two steel plates together with Eastman 910 (industrial precursor to SuperGlue CA). Couldn't pull 'em apart with a forklift. One little tap with a 12 oz hammer and bing, one bonded pair of plates becomes two plates again.

I tried for weeks to get the bar on the bow that holds the spare treads on the Tiger I (I had removed the bar, sawed off the screw bungs so I could put a dozen links of the orig treads in instead the plactic stuff originally supplied). I tried Testors, I tried epoxy, I tried SuperGlue. Yes, I roughed alljoint areas befor adhesion. Nothing worked. It always fell off as soon as I started or moved the tank.

Then WhiteWolf told me about Tenax-r to try to melt the commander's cuppola off to reposition. I tried something similar (Attack) on the spare tread link bar and it is now there to stay. (Handy little guy to have arround, that WhiteWolf is).

CA is handy stuff, but for some jobs, there are better solutions.

Unfortunately, it seems that fumes from ALL the compounds that we use to bond/un-bond parts, while maybe fun to breathe, are very hazardous to breathe......

Best,
