Floor plugs - To weld or not ?

[westoz3.0csa]

Having stripped all the bitumen layer from my floor to check out its condition and give it a coat of epoxy, I am pondering what to do with the floor plugs.:???:

I can't see that they serve any real purpose (other than be a potential entry point for water) and once covered with a new bitumen layer (Dynamat or similar) can't be accessed anyway. I note that any new floor sections are solid and only have the floor plug impression pressed into them.

I am considering welding them or maybe using some adhesive like JB weld or similar or making up a rubber seal and screwing them in.

So ... what have you guys done with yours? ... if anything.:grin:

thank you for your input

I replaced mine with solid pieces - no plugs.

The lore is that these holes were used to drain out excess primer/sealant when the bodies were dipped at the factory. Whether this is true, I cannot say.

So you're right - unless you plan on dipping your bodyshell in paint, the holes don't have any useful function. Most people welding in new floors just use solid sections.

Carl,

I just welded in some round sheet metal flush with the opening. Clean and simple. I suppose if you were going to dip the car then the hole would be needed for drainage (then weld them shut later).

That's what I did too.

Body panel adhesive. Waterproof and no welding or grinding. 4000psi; you'll tear the metal first.

Or if you're feeling lucky- liquid nail. 400 psi.:shock:

I would remove them, clean everything up epoxy the floor and plug and just reinstall them with urothane seam sealer then spray over them with a product like 3M body schutz. Then paint the floor before the tar boards go back down.

+1 to either or both. used body panel adhesive in my 635 and the plugs are nice and tight.
