Hi All,
Just about to embark on some lead loading for the first time in about 15 years (and didn't do much back then).
I've been looking at Flux and it seems you can buy some special flux with lead in it for lead loading but is there any reason I can't use ordinary plumbers flux? I already have some and the data sheet suggests www.toolstation.com/soldering-flux-paste/p73706 that I can use it on mild steel. I'm not looking to achieve the finest finish, I just want to seal the side light pods on my MK2 jag before I use body filler over the top.
Just wanted to check.

You try it but I wouldn't hold your breath - I have never had much success with the everyday fluxes - I use a soldier paste from this supplier - its expensive when compared to the normal fluxes but I know it works very effectively and I hate doing any job twice - link below www.lbrestoration.co.uk/store/Lead-solder-paint-Paste-for-lead-loading-p187418241Unsure if you can find it cheaper elsewhere If this is the route that you go down and require any further info please don't hesitate to post any questions up - Chris |

I will see how I get on with it as i'm not planning on doing much lead loading, only really the side light pods just to seal them up.
I bought a new blowlamps as well with an instant ignitor built in which should make it a bit easier than my old one which I had to light with a cigarette lighter (which I keep losing as I don't smoke so it gets put down somewhere or taken into the house to light birthday cake candles!).

Don't know if I'm teaching you something you already know - paint the paste on (mix it well first) then heat it prior to wiping the residue off with a damp cloth - then apply your lead to fluxed / tinned surface - I tend to apply the paste in small areas at a time otherwise the heat dries the paste out on larger sections - its very high in flux content to the point that rust will form on a bare metal surfaces around it if its not well cleaned off afterwards - I use panel wipe then go over it with the DA to ensure that I have removed all traces of it |

Another vote for the proper stuff and for LB Restoration.
The proper stuff is more than just flux as it tins the surface like magic when heated.
So easy even I could it. Keeping the lead on the car...... not so much!

I remember helping to leadload the rear quarter of an Alvis when I was an apprentice and it was a bloody nightmare.
I thought there was better ways of doing this now and it was a bit old hat?

if i lead loaded my repairs on my mini, the lead would be worth more than the car!!!
