Topic: lead filling

[danijelt]

When you use lead as a filler,wich primer paint do you use?
Thanks!

I would use some epoxy sealer and some epoxy primer.....then paint....

[danijelt]

I restore few Vespa scooters,and they are all mae of metal,an i refuse to use any kind of plastic.
I cut rusty metal an weld new piece,but it would be faster if i could fill in small holes with lead.
But modern primers are not suitable for lead,so i need something else... :'(

I would imagine back in the day they used laquer primer and paint

I really believe if you find EPOXY sealer and EPOXY primer, it will stick to the lead as long as you have the surface cleaned and use a really fine grit paper to etch the lead and surrounding metal.....I have some friends that still do ole skool lead on their stuff and this information is what they gave me when i asked about your situation with the lead.

over here we put tin on it first? we tend to scrape away all the paint, and enough rust to get to the core metal free,
prep it with the famous blue, redcapped bottles to prepare copper before soldering tubes or so..

a piece of jeans with candledrippings of wax on it, to wipe over it after the lead..

once everything is cool and shaped, hollowsectionwax or paint inthere..

I have the impression, that going from lead, straight to the metal is a too sudden change for sheet with poor carbon% or a rusty history..

Totally agree on the loss of metal %.........damn rust makes it so hard to make decent repairs.

All this stuff is above my pay grade

Totally agree on the loss of metal %.........damn rust makes it so hard to make decent repairs.

also the big differences between the types of sheetmetal.
over here the northern sheet lasts, the spain, portugal etc- sheet is gone before you know it.

like if you have a scar through the paint, into the metal, here it takes about two to three days to get that rusted up red.
the good sheet stays like that for years, the bad ones create a hole in about a year or two..

what the lead is concerned, without the tin, the block of lead gets pushed outwards from the moment the corrosion crawls between the two metals..

[danijelt]

what is tin? google translator tell's me nothing.
And thank's guys.

its a sort of metal with a low melting point,

the stuff they use to solder copper tubes for water or gastubes,

I have noidea what the english term for that material is, it looks like lead, also prtty soft, but it grips way better straight on the metal.
and then again, the lead grips better on this stuff than on metal

I must say that our weather forces us to such techniques, putting the lead straight onto paint, and having a somewhat lasting solution is like a dream. Give it say, three years and you can start all over again..

also, completely paintstripped cars.. looks lovely, but you sign in for certain death of the body..

burning tires and producing as much CO as possible in order to heat the climate is our only hope

oh,i get it what it is!

allways thought that it is lead!

Clean surface before with HCl acid? Or something else?

[Samster]

al that is done by the solderpaint, I'll look up a picture

I've done quite a bit of lead work over the years and I use epoxy sealer and an epoxy primer and a general degreaser prep with a non-lint cloth to clean before the sealer .
