You might want to trim the hole a bit to smooth it out. Clean well with acetone and use an abrasive on the surfaces. You should not need the primer. Use a couple of layers of Eternabond 'double-stick' to even out that seam at the edge to provide a smooth transition for the Eternabond tape as it bends over the seam. Then dress the edges of the Eternabond tape with a fine bead of Eternacaulk.

I never heard of double stick , can you explain that or a link that I can read about it. I only know of the reg. Eternabond..Thanks

EternaBond DoubleStick tape when you just need the microsealant

Doublestick is the microsealant material without a white TPO backer. I think that white backer is TPO. Doublestick is just the sticky stuff with the clear silicon release on both sides.

When you have to lay the Eternabond tape (Roofseal) down on an uneven surface, the 1" double stick provides additional microsealant filler to smooth that transition.

When I seal the fiberglass cap to the rubber roof, I leave that aluminum channel there but I use the double stick to make that a smoother transition on which lay down the regular white tape. The folks at Eternabond recommended it.

I also use it when I just need a small piece of the microsealant and don't need the TPO backer. As example when I replace the cargo door holders I cut a piece and put it on the screw threads. That screw hole will never leak again. They sell something like this for screws but it is easy to cut a piece when you have a roll of the double stick. Same with the screws for my folding hand rail by the door. I've seen some serious water damage from those screws leaking. All of those cargo door latch clips that keep the cargo doors from falling on your head leak or will eventually leak. I've resealed all of them on my last two trailers with double stick microsealant on the screws.

Most of the time when I remove one of those cargo door holders or any screw from the sides of the trailer, the factory seal has failed and the screw threads are rusting from water intrusion.

You can use the microsealant like putty and push it into a hole. Since you have used the tape you already know how sticky the microsealant can be.
