Fastest way to stop tail light leakage.

I think a better method is to take the light frame and corner off and apply sealant in the inner interface.  Try that if it leaks again.

@MuttonChops. Would you just put a big glob of caulk on each of  the handle screws & caulk in the other screw holes & around the area where the wires come through & also around the light fixture before putting it back together?

Mine had leakage on drivers side. I put 3M 5200 white around biggest holes then clear silicon around the rest. Here in  Mobile Al we get a tremendous amount of rain and now it is dry inside. This is not for everyone but it sure stopped the leak. Even the wet area inside had dried up and gotten MUCH brighter.  I wish I could have made it look better, but in this 100 plus heat at least I stopped the leak! Art

Definitely would not want to deal with any kind of repairs in 100° heat. Glad the wood is drying out, at least!

For others needing to do a quick repair like this to keep further damage from occurring, silicone and 3M 5200 are both problematic for different reasons. 5200 is the right material in that it’s polyurethane based, which is what nuCamp recommends, but is basically non removable...it’ll never leak again, yay, but you can’t easily go back and clean it up later either. 3M recommends the 4200 instead of 5200 if there is any possibility of eventually needing to remove the sealant.

Silicone isn’t a permanent fix as it eventually degrades or separates from the surface and doesn’t stick well to fiberglass, but it’s also virtually non removable as there will always be a residue left behind that nothing else sticks to either.

Obviously dismantling the area before resealing is best, but it might make sense to keep some 3M 4200 or the equivalent on hand in case emergency repairs are necessary, such as discovering a leak during a multi-day downpour.
