Rated 5 out of 5 by from Makes tinning easy This lead bearing tinning butter works great. It must be applied to a very clean surface. Very very clean. Any contamination will cause blackened areas which need to be re-cleaned and tinned. I recommend using scotch-brite and naptha to scrub the area to be tinned until the heat effected area is shiny and not showing any black carbon contamination in the weld areas. The scotch-brite pads will also scrub out any flash rust. No tinning is going to be successful if there is any contamination of the metal. After scrubbing with scotch-brite and naptha, I take a clean rag and wipe the area down with naptha again. Fold the rag over to get a clean surface and repeat 4-6 times until the rag is not picking up anything. Brush on the tinning butter and hit it with a medium flame. Once it starts to turn orange and you can see the lead melting in it, swipe it with a rag. It should leave a silver surface. It should look completely coated, no black areas or burned spots. Cleaning is very important! This is a great product.

Rated 4 out of 5 by from Good product if your into leading fender ect have used this product on several motorcycles and cars . Easy to use and beats the use of liquid acid for tinning and is much safer in my opinion. Bear Bryant

Rated 5 out of 5 by from works better then expected After years of working in electronics soldering components, this was easy since the same principle applies, just on a bigger scale.
