Introduction to Body Soldering

Traditional lead-based body solder has been the choice of restorers and customizers for over 80 years for filling seams, leveling uneven body work and blending in custom features. Even the best polyester body fillers available today cannot match the superior adhesion, strength and overall durability that body solder provides.

Before doing anything, make sure your panel can be soldered. Click here, for more information ...

First clean the area to be filled, back to bare metal with a Stripping Disc, Abrasive Sandpaper etc.

Brush Solder Paste over an area slightly larger than that to be filled and heat the area gently until you see the solder paint “tin” the panel.

Remove excess solder paint with a clean cloth.

Next, melt blobs of body solder onto the panel over the area to be filled.

Prepare your Paddles by warming the surface of the Tallow and wiping your paddle in the molten puddle.

With a suitable amount of body solder now deposited on the panel, heat it carefully until it can be spread like butter with your paddle.

Control heat carefully and keep spreading until body solder is evenly spread over area.

Wash with cool water to quench and to remove traces of acid solder paint. Don’t grind or sand, use a Flexible File.
