You can get two different types from here.

They are also very good to deal with (the archerfield one. Can't vouch for the others)

I use this one by the way.

Really good stuff, leaves a lovely copper colour that made me want to clear coat it.
$25 per can.

Primer


I bought the gear that you recommended Brad - Matt couldnt find your stuff. Like always you go in for one thing and walk out with six.. the kids can eat baked beans for a night or two.

I will get some pics up tomorrow if I get home in time - I quickly applied some afternoon, but was too late for photos.

I can see why you liked the colour.

Cheers

Peter

I have found ti does work well and does not seem to affect the weld that gets layed down on top which is good.
As far as long term protection, I don;t know. I figure it will be good to have in the sills and folds that I wont get to later and being copper based, it should by rights, melt and then solidify as part of the weld when it cools.

I know VW used to braze certain areas like the roof to a pillar join, but then VW also made a bunch of cars that rust to buggers after 30 years? So who knows???

Hi Guys,

When you apply weld though primer, is the idea to keep it very thin, or is it not such an issue?

I was planning on applying weld through primer to the tunnel lip before fixing new pan halves.

On some test pieces, the plug welds look ok when it is on bare metal, but when I use Camweld on the tunnel lip,they look down right crappy and at times leads to the top plate burning away.

Cheers

Newt

I find the Zinc based weld through primers to work well with electric resistance spot welders

When doing MIG plug welds I find that Copper based weld through primers spatter less.

I have only used copper.
You could get around it by giving it a good coat behind the steel then tacking in place before giveing it a light scrub on the weld join from the outside, cause at the end of the day you will be sanding/grinding the weld flat anyway before paint.

It really just gives us a warm feeling knowing the back of the steel has some protection incase we accidentally miss the area with fish oil later.

I do the same using zinc weld thru, works well for me.
