| In the September 2003 Mechanic on Duty section, Welco 1509 solder with Welco 380 flux were recommended for filling pits in pot metal, zinc die castings, prior to replating the chrome finish. After over an hour searching on Google, I am unable to locate any current source or information for these products. I found references to a company called Thermacote Welco, located in Kings Mountain, NC, which was the manufacturer at some time in the past, but the phone number is not in service and apparently it has either changed its name or gone out of business. Can anyone help? Does the author of Mechanic on Duty see these postings? Any other solders used for this purpose?

| You might want to check out the December 05 issue of Street Rod Builder magazine. It has an article on chrome plating. Try silver solder,but practice on scrap first.www.street rod builder.com .Hope this helps.

| Hey I found a company MUGGY WELD " muggyweld.com" They have rods with low melt temps, which can be used prior to replating. I need help with how to repair an already "replated grill" with pits on the inside, without distroying the new chrome, as the pits can be seen when installed on the car, as you look downward at the grill.

Thxs oldguy OldGuy; Sorry to say, but you are going to have to "unplate" your part before you can fill the pits.. Muggy Weld will work, so will good ol lead solder & flux.. the key to filling the pits is cleaning them.. Any oxidation left in the bottom of the hole will result in the solder falling out.. same as if a dentist filled a rotted hole in your tooth.. Gotta grind away the rot (a Dremal type tool works best), get down to fresh, clean metal, then fill the hole with solder.. After that, the "real work" begins.. lots of sanding (by hand) to smooth that solder to "glass slick" prefection.. Once that is done, the Pot Metal part MUST be cleaned some more before it can be plated.. Pot Metal also requires "Zincating" before electoplating.. if your area plater knows his butt from second base, you shouldn't have a problem.. Caswell.com is a hobby plating site, while I would NOT recommend you "dive in" and do the plating yourself as it would be cost prohibitive for a single item or a large item, you can read the forums, "How-To's", etc. and become more knowledgable about the process.. this way you'll know and understand what the plater is doing, and if he is doing all he is suppose to..
