For those DIY enthusiast’s that want to replicate original panel jointing with lead instead of Bondo filler here’s a little tool I found at Harbor Freight that has helped me a lot. Additionally I sourced a connector hose from my local Krap-Mart, Camping Section. Their web site had a more generous supply of hoses/lengths to choose from if you need a longer hose…
You can connect this little gem to a LP bottle ( I used a 20# from the grill) and Lead-load until your hearts content. I found the self-igniter especially nice.
I believe the model is TS4000 with a Harbor Freight SKU: 91061. For $20 bucks you can’t go wrong.
Stay Well and Happy Trails,
Dick
