Used this 3M tape to add some $5.00 wrecking yard factory fender flares to my 2007 Silverado Classic Needed to cover that Silverado (GMT 800 body) wheel well rust we all know and love so well.Installed this past summer (July 2023) and going strong six months later. The truck sits outside 24/7/365 hand has seen 90+ degree days, 20 degree nights, rain, and snow since the flares were installed and still holding like day 1. Several long highway trips with plenty of wind and no issues at all.In my opinion, the key is good preparation. Removed all of the original adhesive tape from the flares (not easy). Cleaned the lip where the tape goes with acetone (don't go crazy as acetone can melt ABS plastic). Scuffed it up with some ScotchBrite and cleaned with acetone again. Affixed the tape to the flare with the red film side out. Take your time and don't try and stretch the tape. Press down on the tape thoroughly to get a good bond.You MUST leave a "tail" on one end of each piece of tape. I left about 6 inches but this was far too much - but it has to be enough that is reachable with the flare positioned on the truck. From the "tail" trim off and remove the foam tape but leave the red film intact. You can use some masking tape to tape the red film tail to the front of the flare after you remove the foam adhesive.Now, dry fit the flare to the truck to see where the tape will land. Clean these areas well. I used acetone to remove any wax or grease but, again, don't go crazy as acetone is strong stuff.Did the work on a warm, sunny day. Left the flares in the sun so they would be pliable and thus much easier to fit.Place the flare on the truck and hold it in place while you pull the tape tails to remove the film and expose the adhesive tape. Do one piece at a time and make sure you have the flare in the correct place - you only get one chance to get it right. Press gently but firmly on the flare as you remove the tape film to adhere the flare to the truck. I did the top first, then the front side, than the rear. I did this alone but an extra set of hands is probably a good idea for this step.Lastly, attach the inner part of the flare to the lip of the wheel well using plastic fasteners. Because I had a fair amount of rust (missing metal) and I was also putting in wheel well liners it required a bit of creativity. I used a combination of plastic body rivets and christmas tree style plugs. Get yourself an assortment on Amazon as every truck is different.The pictures show the finished install. Sorry, I did not think to take pictures while doing the work. As you can see, the tape is holding well and the flare is solidly up against the body all around. These were taken 6+ months post-install. Also, no, the flares did not look that good when I picked them at the yard. Freshened them up with some Dupli-Color trim and body pained (item TB101) available on Amazon or any auto parts store. All in all, for les than $45.00 in parts (including the flares themselves) I don't think it came out bad at all. Far better than the rust they hide that is for sure. The 3M exterior attachment tape is a winner as far as I am concerned. Could not have done the job without it.
