Getting ready to put down a plywood/eps foam 'sandwich' floor. I need to plug the threaded holes that previously held the seat cleats. Anyone had experience using spray foam (great stuff) for this purpose?
I know welding them up would be optimal.... But it seems like for just sealing that great stuff might be a 95% solution.
Could just pack the holes with seam sealer... cheap and easy with no worries about rust.
But i like the idea of putting a bolt it too
This is the route I'd go----the bolt IMHO doesn't do much to enhance the sealing exterior grade silicone sealant/adhesive or autobody seam sealer already provides. Keep in mind the underside of the floor pan doesn't see much if any "action" like water being thrown against it when on the road.
