Mounting things to the windshield

[Cantdecide]

Hi Guys,

I'm thinking of getting a dashcam and possibly a radar detector, but I'm worried about using either suction cups or glue on the windshield. I've see suction cups eventually leave permanent marks on glass, and I assume glue could be just as bad.

Has anyone come up with a good solution for this?

If the suction cup and windshield are clean, there is no reason for a suction cup to leave marks which windex cannot remove.

I have mounted my radar detector on my rearview mirror stalk.

I have a similar concern. I have a phone mount (windscreen suctioncup) which seems to last about 1.5 hours before falling. I've cleaned the surface, tried alternate products and nothing. I want to be able to reliably mount this for auto-X and track. I AM willing to use an alternate adhesive as long as with some work, it is removable.

when trying to mount suction cup devices, as long as window is clean, the only time I ever have problems of cups coming loose is when window is cold, so I will put defroster on till temp comes up and then they usually hold, but I have moistened with fingers tips and that also has worked but not if glass is too cold

Your phone mount is either defective or poorly designed, then.

I have a good locking suction cup mount. It keeps a 0.5lb datalogger attached to my car while subjected to 1.2Gs in all sorts of directions for 30 minutes at a time.

The only time it will loosen is if I put it on in in the shade and then move the car into direct sunlight for a long period of time. But, that's to be expected.

I don't know about Evoras, but the Exlise windscreen is pretty concave near it's lower center, so sometimes - particularly in hot weather - stuff can fall off.

Can't imagine a permanent mark on w/s, but one could try BonAmi, an extremely gentle product. I use this every other time I was each car; it removes the crap diesel trucks can spew onto w/s.

On the 7, I used 2 pcs of Velcro to mount stuff; unaffected by temperature.

Is Mount Guys still around? Heard they had good products.

This works good on my Evora. Once and a while one suction cup will come loss.

A thin amount of vaseline will last longer on a suction cup than spit.

I think I suffer that problem, I mount it in my garage, then drive out in the sun.. probably my own fault, still does not exude confidence.

vaseline?

[brgelise]

I do not recommend drilling. That would leave a mark. Never heard of a suction cup leaving a mark before!
