Double sided tape with a strong enough adhesive to bond side mirrors to the painted sides will be a problem if you want to remove the side mirrors. Likely you will kink and bend the side mirrors during removal. You will also likely remove the paint from your side panels as the the tape will grip the side mirror better than the painted surface, which means your paint will go.

It is a lot easier to remove three small screws and cover the holes that are below the playfield than to deal with attempting to remove a double sided tape installation.

The reality is, an installation using screws is easily removed. Using double side tape is more permanent and can remove your paint, maybe even wood when attempting to remove the side mirrors. Further, adding the double sided tape further increases the chance mirror damage as this will reduce your side clearances - X2 the thickness of the tape.

It's your machine and obviously your choice, but using double side tape is not a good idea.

I guess you didn't try to remove the mirror blades then.......

I am sure the double sided tape holds well. But your comment was you wanted to remove the side mirrors, and that is where you may find some difficulty and damage using double sided tape.

If you like it, do it.
