5200 Adhesive sealer liberally sprayed with tap water

3m 5200

Do you need a few screws or rivets to hold the mirror in place? What do you mean when you say "sprayed with tap water?"

3m emblem adhesive tape (2 sided tape). I put the hatch mirror (acrylic) on my 31ss in 1998, spent all its time in Lake Ontario and now Lake Erie. It's still there with no problems.

I would be concerned that anything other than double-sided tape would screw up the mirror coating on the back side of the acrylic. The proper double-sided tape will do the trick.

I used 3M automotive double sided tape and it has worked great for 3 years.

industrial velcro

I don't get that water thing either.

But thanks.
I'll try thumb tacks.

I can tell you what not to use, from experience or the lack of.
