Got a Wald spoiler and a Myride diffuser painted. I can't decide which double sided-tape to use.

The 3M VHB (probably strongest tape out there) or the outdoor 5lb tape 3m

I just want to make sure that the spoiler or lip come off.

 

As long as you clean the parts you're going to apply the double sided tape on you shouldn't have to worry about any thing falling off. Also some guys like cutting the double sided tape into smaller sections instead of using a long piece, I think the reason is to have better contact points.

 

Use rubbing alcohol wit 3m 5-10lb double sided tape I'm in New York I get mine from Michaels craft store from picture
Frame section note if using rubbing alcohol once you lay it down its stuck lol I learned the hard way 2nd time was a charm I had 2 15" kicker L7s vibration was crazy and held up no problems with wing..

 

An autozone near me sells automotive mounting tape that I used for my spoiler. It's stronger than the 10lb double sided tape I've tried in the past

 

Picked up a roll of 3m extreme heavy duty tape for 9$ at Lowes. Only 60inches. Ridiculously expensive. Probably need 4 of those to install everything

 

This 3M tape is amazing.
You might be able to find a smaller roll locally.


Make an even stronger bond with 3M adhesion promoter.

 

Lol just buy one at o Reilly it's like $8

 

honestly any of the 3m double side tape would work. i did long strips and when i tried to take it off, it was a bishhhh!!! had to use fishing lines to cut off the tape.

 

just as long as you need adhesion promoter

 

home depot has 3M TAPE outside use hold up 15lbs

 

Yeah, only heard good things about the VHB but jesus christ, $35 for a roll of tape is ridiculous.

Well I picked up the extreme 3m heavy tape rated for 20lb. Gonna give that a shot and see how it goes.

 

I heard that heating up the double sided tape until it melts with a heat gun or hair dryer gives it the same affect as the adhesion promoter.

 

Installed my rear diffuser. Everything went well except there is a minor gap. What could I do to get rid of this? Some sort of glue?

 

3m double sided extreme outdoor stuff from home depot. its super strong, youll need to apply heat if you ever want to take it off. I use it on any temporary mods on my vehicles.

 

Did you check fitment before you got it painted? Always test fitment before peel off the tape. I would start from center to both side. Like i post before, home depot has outdoor tape could hold up to 15lbs (black one hold up 20lbs).
