How to prepare trunk lid for attaching spoiler

[shagnat]

How should I prepare my trunk lid for attaching a new "spoiler" lip to my trunk using the 3M tape which was provided with the lip?

Any input is appreciated.

I would just make sure you have a very clean surface. (clay & polish). Kinda scary just having 3m tape holding a spoiler...

Yep, a good polish and alcohol wipe down will prepare the surface for proper adhesion. If the surface is cool to the touch, then use a heat gun to warm things up for strong initial bonding.

Warming things up with a heat gun is a great idea I hadn't thought about.
Thanks!

Hair Dryer works too if you don't have a heat gun.

Don't get the 3M double sided sticky tape too hot, just warm. I would also warm up the trunk lid/paint using the hair dryer or move the trunk into the sun.


Prep paint just like you would for a coating, the is clay, polish, strip.

besure to do a good ipa wipe down so adhesive sticks, heat is a very good idea escpecially on cold days.

Also, be sure to put some weight on the spoiler to keep pressure on the adhesive. Unless its a very small spoiler i'd use more than 3m.

Some cars do have very small spoilers that 3m tape would be sufficient, do you have a picture of said spoiler?

To those aprehensive about the 3M tape, aren't most factory lip spoilers just stuck on with double-sided tape? That's how my sister's Lexus IS is. What am I missing here?

good advice - getting ready to do this myself. BMW 328xi.

I installed a lot of body kits with 3m double sided tape (front lip, side skirt, trunk lip/spoiler, rear diffuser).

The tricks I follow:
- do it on a warm day
- dont get the tape hot until you have the bodykit lined up to exactly how you want
- ask for someone to hold it while you line up the kit
- don't cut out a single long piece of tape, it is easier to peel off with two to three smaller pieces instead
- peel a corner that sticks out from each piece of tape
- once everything is lined up, pull on the corner and take off the plastic attached to the tape
- press down and use heatgun/hair dryer
