Buy some and see for yourself
Your review: Everything I've used this on has held. It is really a superior adhesive for plastic. I've repaired a crack in an interior panel on a car, to repair a broken plastic pull grip on an extension pole, to held a permanent magnet to a Kobalt light tool (it had 4 but they were not strong enough), and many other things I can't quickly remember. If you do a lot of handy work you ought to get one and have it available to try the next time you need to glue plastic.
