Trying not to call out particular people, but:The rubber cement instead of CA glue was discovered when I was doing a Fi softparts on XXX motor for Quakeroatmeal.
The first time I tried to glue the spiders on, the 'glue' didn't ever set up. I thought mabe the nice paint coating was keeping the glue from sticking or MAYBE I used too much accelerator. We pulled it all off and ground down both the surround and spider landings. Re-glue, SAME SH!T. I said 'it's acting like rubber cement!" sure enough, that's what it was. We opened the second bottle, same crap in it. At this point, he was screwed.
We sanded down as much as we could on the spider to remove the CRAP that was sent to hold the spider on. I went in and got some of my extra DD glue and fixed him right up.
