Replaced roof molding screws

It would if it was leaking around the screw. I also need to make sure the gutters aren't clogged. I think that is what caused the leaks.

My trailer is 18 years old and the only screws that were Rusty was where it had been leaking. The other ninety percent were like new. If you found Rusty screws my guess would be that it has been leaking and new screws won't fix that. JMO

leave the screws alone. if it ain't broke, etc., etc. etc. if removal is ever needed, drill them out. but yes, 5200 is probably overkill. :)

I replaced all the screws in the molding holding down the rubber roof with stainless steel screws dipped in 3M5200. That is a lot of screws!



Do I need to do anything else? Run a bead of sealant at the top of the molding? Cover the entire molding with Eternabond? I can't see either one of these would be an improvement on the crews heavily dipped in 3M5200

About 3/4 of my screws had rusted threads. On mine, a clog in the gutters caused water to rise into the screw area. I can't see that the plastic screw cover does anything but make the moisture hang around longer. My rig just turned 10. I wish I had done this 9 years ago.

I'm not sure I would have used the 3M5200 since that is the strongest and most permanent marine adhesive/caulk made by 3M and it's bond is never meant to be broken w/o significant damage to the surfaces. I would be concerned if I had to ever remove a screw. You might wait like a month and try and remove one and see if it's even possible.

I like to use the Eternabond adhesive from their double stick tape on the threads and then put a small patch of Eternabond over the screw head on non S/S screws to seal the entire threads from moisture. In your case with using S/S screws there is little extra protection added with adding the Eternabond over just the screw heads.

If others are thinking of using a 3M adhesive/sealant like you did I would recommend looking at the 4000 series which is less strong and is designed to be removed if necessary. You really don't need the adhesive strength in this application anyway.
