I've used the gel on dandelions in the lawn and it's fine - it works and doesn't affect the grass as long as you're careful and only put it on the weeds.
I've killed bindweed with Roundup Spray - you need to put some canes in the garden and encourage the bindweed to grow up the canes. Then mask off your plants with sheets of cardboard and spray the bindweed. Leave the bindweed until it goes brown - that indicates that the active ingredient (glyphosate) has travelled back to the roots and killed them as well. It sometimes works better if you bruise the leaves slightly before spraying.
