Circular Floor Pan Plug (seal) attachment

Paint any bare metal with a rust resistant paint first and then glue the plugs in place with a 3M body caulking (available at any body shop supply business) called “fast & firm”. You may be able to somewhat duplicate the factory look by quickly dabbing an acid brush wetted with lacquer thinners straight in & out of the caulking but try it on some caulking spread on a scrap piece first to develop your technique ;). ~ John Buchtenkirch
 
John,
a) Is using a rust resistant primer okay ? Do you have a favorite brand ?

b) How about the underside of the circular plug ? POR15 ?

Thanks
 
I’m not big on recommending paints to people because of the ridicules statements the companies make like “it stops rust dead” when in reality all any paint does is slow corrosion down considerably if done correctly . Having said that POR 15 isn’t bad except that it doesn’t like to stick to new shiny metal, it almost needs a bit of surface rust or abrasive blasted metal to hang to. POR 15 dries shiny & smooth, sand it slightly with fine sandpaper and then blow it off so it has some teeth for the caulking to grab. I blew Dupont Vari-Prime into all the sealed up panels (rocker panels, door posts & such) on my coupe where I can only hope the phosphoric acid that’s in it will slow down that rust monster :?:. ~ John Buchtenkirch
