Need Advice - Yofer Rear Spoiler Install

[SlntHntr27]

Hey All,

I am looking for some help here and hope some may have experience. I am looking to install this Yofer Spoiler on my 2023 Civic Sport.

It can be bolt mounted or you can use the doubled sided adhesive tape that it comes with. I have already decided not to bolt mount for a few reasons. With that aside I was hoping someone could help with the adhesive side of the things.

Do I use the provided adhesive or do I use a 3M aftermarket tape? Here are pictures of the base of the mount and the provided adhesive pads. Or should I use something like the 3M tape linked below which I have and already used on my front lip and window visors.

Amazon.com: Double Sided Tape Heavy Duty, Waterproof Mounting Foam Tape, 16.4ft Length, 0.94in Width, Strong Adhesive Tape for Car, Wall, LED Strip Light, Home/Office Decor, Made of 3M VHB Tape : Office Products

Any advice or experience would be greatly appreciated!
Thanks in Advanced and Happy Holidays!

I would go with the 3M that you provided the Amazon link for. I deal with adhesives every day. Our applications are sticking bare metal to bare metal (so no painted surfaces). The Amazon link does not give a 3M part number that I could find but that item is part of their VHB line (very high bond) and should be good for this application. It is amazing how strong of a bond you can get from 3M VHB. The adhesive supplied with the wing is too much of a wildcard.

Surface prep is just as important as adhesive selection. I would use a clay bar and then isopropyl alcohol wipes. If you just have the alcohol wipes I would do multiple wipes - like 5 or 6. Sometimes just a wipe or 2 will not remove a thick layer of wax and contaminates.

3M also makes a primer that you can buy on Amazon that can significantly increase bond. Search for "3M Primer 94." Should be able to get it in an application pen.

Thank you for the detailed explanation it was exactly what I was looking for. I felt the same way about the supplied adhesive and seeing as I already have the good 3M tape I might as well use it. I didn't think to use a clay bar but I definitely will and then isopropyl alcohol. I feel much more confident that this will not go any where once applied and cured. Now to make sure everything is centered ?

Thank you! I have never heard of this and I will for sure use this in conjunction with the 3M tape. Happy Holidays!

Hey All,

Been awhile but confirming success on attaching the spoiler.

The parts of the spoiler that would touch the car on the Yofer spoiler are not flat. I used multiple layers of tape till I had a flat and even bottom so the spoiler touch points would be even. (The Yofer spoiler as a raised ridge around the base and making it entirely flat made for a more secure connection) After measuring several times I used painters tape to use as guide lines to center the spoiler and know where to place when attaching. I placed several heavy objects on the spoiler to help keep pressure down while the spoiler cured. I did use the primer both on bottom of the yofer spoiler and on the trunk of the car when attaching for extra bond. I left the car in a garage for 24 hours at an average temp of 80. You can look up bonding times based on the temp your car will be in.

I attached this during December and it is still on the car with an incredibly strong bond. I took a chance and even took it through the car wash several times now and it is securely on the car.

Overall I think it came out great and appreciate all the advice given. My suggestion here is take your time and make sure you give this time to bond in an enclosed area.

Thank Again!
