Did you use a sealant on the bolts/bolt holes to prevent leaks? I read on a taco forum Lexel is a good product to use but I wanted some feedback from member here.

 

[TomEf]

I did. No leaks so far.

I installed my dissent roof rack a few weeks ago. I used a total of 4ml of RTV (for all of the holes combined) around the outside of the holes and on the bolt threads. I also used butyl tape on each of the "feet" for the new rack.

I used new gaskets and bolts/washers from Toyota.

I installed a prinsu rack and used permatex number 2 sealant on the bolts with zero leaks. I live in Florida where it rains all the time. A leak is the last thing I want.

Prinsu 200 Series Rack INSTALLED

I was able to get mine on yesterday without any issues. I'm pretty impressed with the rack, once everything is together it's very solid. I took it for a short drive only up to about 60 MPH and the wind noise is very minimal even with the sunroof open. I am running the fairing at the lowest...

I have a Gamiviti rack and it was recommended to use DAP Dynaflex Ultra...no leaks and super easy to use!

I used 3M Clear Super Silicone Seal after doing a bunch of research. It is "excellent for general purpose bonding and sealing, as well as formed-in-place gasketing applications". Read more to see why it is perfect for this application. You can find 3oz tubes if you look around.

yes, a low yield thread locker on the bolt threads, and Ultra black on the surrounding areas..
No issues.

Ultra-black comes in a easy dispense canister

RTV, tends to be scrapped off threads, so it's not a great choice for the actual bolts... works great for the area surrounding them and is pretty easy to clean off.

I’m planning on using Loctite blue threadlocker for the bolts to prevent backing out.

Thanks all for the suggestions.

Might be late too late on this one but I would not recommend that. Locitite is literally the root cause of any/all "nuts fell into the roof" stories that you hear about. Specifically one bolt gets removed, then the other gets twisted, and the path of least resistance is the whole nut carrier thing popping free and spinning, rather than the bolt coming loose. the way to avoid the issue is alternate between the 2 bolts on each tower, back them out evenly then it's never been an issue. But your new bolts will be under load from a rubber sealing washer, surrounded by some type of sealant, they really shouldn't magically back out somehow.

Thanks for your advice, especially the video you posted on YouTube regarding removing the bolts. I did end up using the blue locktite on the new screws, and I guess this is down to paranoia from when I used to race bikes. Obviously track conditions are more demanding than the street but considering the process you outlined in the video worked so well I was ok with re-applying the threadlocker.

Anyways, thanks again for posting that vid, I wouldn't have attempted the swap if it wasn't for it.
