Johnson's OR-550 Soldering Paste and Lead-free Body Tinning Paste are designed to work together with Johnson's No. 523 composite (semi-solid) Lead-free Body Solder. Applied correctly, these products enable the fast tinning and soldering of both plain steel, as well as the electro-galvanized coatings used by the automakers today.
Using OR-550 and No. 523 together, along with the proper technique enables the filling of seams or dents without voids, for final sanding to class-A finish. Also recommended for rebuilding antiques, collectibles and vintage cars, where plastic fillers may not be desirable.
The OR-550 flux that is common to both products provides powerful cleaning and tinning action, works as a paddle lubricant, and then completely washes off, quickly and easily, leaving an uncontaminated surface for sanding. Some technique is required, but definitely worth the trouble!
