How to get it to stick.

Hi Petza, try genuine 3m double sided tape... the sort used for external automotive fittings. I use this for GPS (on dash) and dash cam (on glass) and have not had any lack of adhesion probs so far. You can get this stuff on ebay, in various widths.
Cheers

After going on the GRR my Battery monitor fell off the dash multiple times - My solution was to use a little amount of clear silicone & stick it to the dash. I had to take it out of the car when i sold it so i just twisted it off & cleaned the remaining silicone off.

The first thing with all double sided type tapes is that the surface must be clean, and that means some sort of solvent wipe.....there lies a problem a solvent that will not damage the surface, is agressive enough and evaporates cleanly.

It will vary from plastic to plastic, but white spirit is a fairly safe bet.

second is adhesive compatability.....different adhesives have better performance on different substrates......differening plastics can be an issue.

most of the commonly available retail double sided tapes are pretty pedestrian in their performance all round....regardless of brand.

I had an issue tyring to get some LED strips to stick to my fibreglass canopy.....I went thru 4 different types of double sided tape till I got one that was compatable.

If you go to a auto refinish supplier, they will have auto trim tape...this is used to refix protector strips and the like.


There will be a type with typically a green backing, this will be either acrilic or butal rubber adhesive...don't bother.
What you are looking for is the stuff with typically red backing and is a Cyanoacrillate adhesive..(yess it is related to suerglue).

This will be called something like high bond strength tape.....in Scotch it is called VHB ( very high bond strenght tape0.

This is good stuff & is compatable with a variety of non pourous substrates, fabulous on glass ( it is what comes on toll transponder mountings)....but it aint flash on bare timber or paper.

This is realy good stuff....make sure you clean both surfaces and you do not touch the sticky face.

cheers

Silicon should work for you, much better than any double sided tape.

I have used it to fasten the bracket holding the remote head of my transceiver to the centre console.
Hasn't budged in the four years I have owned the vehicle.

Sticky backed Velcro is what I use - the sticky side is very good.
I use metho as a solvent to prepare the surfaces.

self tapping screws work well also. I've been on all sorts of bumpy roads and it hasn't wiggled even a little bit.
