MollyB responds re: Mainship 390 2004 aluminum slider threshold
OK, much appreciated all your responses. The threshold is what the sliding glass doors rest on...not sure its the nautical term...someone had already painted without priming...so we scraped it down to the alum. and thought we'd try just naked alum...with perhaps a wax...? The rollers are a little iffy so we'll keep in mind the teflon...thanks, Johnma...stainless may be the way to go next year...
