When I bolted the walls down to the trailer frame I sealed the wall/floor and the bolt holes with silicone. Big mistake, which I corrected later in the build and used urethane based sealers for everything from then on.
When towing in heavy rain this week, I had water come up through one of the bolt holes at the front of the trailer and make a minor pool on the interior floor. Since it is too late to change the sealer I used (and the trailer body cannot be detached from the trailer deck anymore), I am thinking of using something to cover the bottom of the bolts and washers under the trailer to seal the leak. What would you use?
Rubberized undercoating?
Sikaflex caulk?
PL Premium?
Something else?
Thanks for your advice and experiences.
