I have a glass shower door with 2 magnets (1/4" x 1 1/2" approx) and one of them keeps coming off. I tried all kinds of "water resistant glues" and none of them work, Is there anything that will? There is no company name on the shower itself. I tried contacting the builder of the home but got nowhere. Any suggestions? Thanks in advance.

3M makes a good Marine Caulk/Adhesive called "5200"
Great stuff.

Use rear-view mirror adhesive from the auto-parts store.

I would use cynoacrilate (CA) glue. Comes in thin, medium and thick. You will need either the medium or thick for their gap filling properties.

You will also need the accelerator. The thin is almost instantaneous drying, the medium and thick are not, therefore you need the accelerator. Put glue on one surface and spray other surface with accelerator. If surface is magnetic the magnetism will hold in place. If not clamp with small spring clamp. Spray again with accelerator. Give a few minutes to dry.

CA glue available at hobby shops and woodworking stores.

The rear view mirror adhesive is specifically designed for a glass to metal bond. http://multimedia.3m.com/mws/mediawe...SevTSeSSSSSS--

If the Crazy Glue works good, great, Looks like I got out voted. If not,
The 5200 works great in Harsh Marine environment, would think it could work in a shower.
Good Luck.

Use GE silicone clear. Hold Magnet in place w/blue tape until silicone drys, 4-6 hours. Will hold almost indefinitely in shower.
