which 3M double-sided tape to use?

tboooe · 03-20-2015, 11:04 AM

Most people say use this one, part number 6384:

http://www.amazon.com/Automotive-3M-...ble+sided+tape

But I cannot find any specs on this tape on the 3M website, in fact I cannot even find this part #. I have been reading that I should be using tape with holding strength of 20lbs to use for applying various body parts like spoilers, splitters, etc.

On the 3M site I found part # 5344 but this doesnt seem to be widely available. I also found part # 5952 but the 3M site says its for electronics applications yet I see it on the web for automotive?

I'm using the same one - got it at Home Depot. You will need two rolls.

Thanks guys. The 3m site is a little confusing. There are so many part #s and applications.

I tired to fit my spoiler today using 3m tape 3M VHB RP25 0.6mm x 12mm.

Firstly I didn't find the tape very sticky. Is this normal?

But the main issue I had was the the spoiler isn't flat, it kind of has a lip on it so the tape wasn't thick enough to bridge the gap between the spoiler and the body work.

Anyone else had this issue? What should I do just use thicker tape?

Its the one with the red plastic backing for automatic applications. I think they call it molding tape.

Try UK eBay. Just search for 3M Molding tape. In the US tons show up, so I'd guess in the UK quite a few would too.

No idea. Its OEM though. Its the tape all the manufacturers use to put on side skirts, air dams, body side moldings and spoilers.

I went to go look at the package the tape came in (still have it) ... funny thing, there was no 3M part number on it at all

Its got the red backing on it thats as hard as hell to take off when you are getting ready to apply it - 3M/Scotch Extreme Mounting Tape

Thank you! Would you mind measuring how thick that is? My concern is that it looks a bit thick for what I need it to do. The other 3M tape that is supposed to be for automotive molding is only 0.045" thick but I am not sure if it has as much strength.

Thank you! So I've been doing research and I found another 3m tape that is even stronger than the Extreme Mounting Tape. According to 3M the 5952 tape has a static shear force of 4.4lb/in^2.

It's only $12 for a 1/2" x 15ft roll. Just Google 3M VHB (Very High Bond) 5952 to read more about it.

4.4lbs/in^2 is shear strength which in my case is not really applicable since I am using this tape to apply the M4 side sills. However, I expect there is some direct correlation between shear strength and moment force resistance.
