I think I said that somewhere. But I used E6000 under all of my tabs anyhow. PLastic weld will snap right off, with out some E6000 under them. I only used plastic weld around the edges, just for esthetics. E6000 will do the job just fine, just clamp 'em down. The stuff really grips it pretty good. Also, I always scuff up both surfaces with some sand paper, to really give it something to hold onto. When it's smooth, it's more likely to pull off.
