Installed my Wald "Style" spoiler today...
#46
Good to know! Is there any adhesive or trim to install where the diffuser meets the paint? I've noticed a few F owners with the Tom's diffuser using that trim to avoid debris getting in those tiny spaces, but I haven't seen any of that trim with those who have the WALD diffuser
I pulled it back off and fiddled with it, but could not get the gaps to settle on both sides (near each end).
So I went and just ran 3M tape along the entire front surface. which helped with the side gaps, and created a uniform fitment.

Nice pick up...I don't think you should coat your diffuser any of the top brand name ones come witha good clear coat already on that is UV resistant and the exhaust will not damage it either. Leave it be as is and enjoy your dope diffuser

The diffuser is also held on by those two rear deflectors (from the Highlander - should you lose one)...so you will need to drill, they're length is very short and they just barely fit through the bumper - so you will need to drill 2 small holes through your bumper - they are bolts with nuts. There is also two small screws for the bottom of the diffuser as well. This is the main reason why you will need to remove the bumper completely to install this properly.
You can see the hole here, with the reflectors removed.
There is also two small screws for the bottom of the diffuser on each end that go through the bumper as well.
I used Permatex Ultra Gray High Rigid/ Torque just along the top - where the gaps were.
The rest of the diffuser, I use 3M foam tape.
The RTV sealant has not shrunk, peeled or separated at all for the last year/ including two track days.
