Just curious if anyone ever used it... I'm mating the inner/outer rocker together. Thought about spraying the seam where two mate. Then go back spot weld the inner along the seam.  |

Interested to see about this. Could be useful once I clean the HP30 to keep it from rusting while I'm saving up for the gears.

Weezie, I'd spray the HP30 with some epoxy primer, then clean off the the sections prior to welding on the brackets.
The only spots I'm looking to use the weldable primer is where I'm mating sheet metal that is being spot welded together.

We used it on all my truck panels and it welded just fine. I bought the primer with Zink to stop the rust and it's weld thru.

Question??
Are you using the primer in an area that you wont be able to paint once the panels are welded together? If so when you weld, won't the heat from welding burn some on the primer away and you will still have bare unprimed metal?
I hope that makes sense?

Greg,
Yeah, that's were I'm looking at spraying it. That makes a ton of sense. I've read that it melts and reforms around the weld, not totally burn away. I call B.S., but I'm just trying to get as much coverage as possible. Especially in the rocker panel area...

Funny that you posted this. On a recent episode of Graveyard Carz, Mark was talking about this same thing. Said he has his guys spray the weldable primer on all the surfaces that they won't be able to get to after the panels are spot welded together. He swears by the primer and says it does in fact return to the welds and seal them up. Don't know if this helps or not....

This is interesting thing to know. Of all the things I've learned over the years, I never learned anything about body work.
So the theory is that as the welds melts/softens the primer it slows back around the weld area as it cools and reseals it.

I bought it a Advance auto. It appears that each store only stocks two cans at a time. I watched a bunch of videos about it and did a lot of research on welding forums and it seemed fairly unanimous that was that way to go. The zinc will also stop any existing rust.

Here's what I ended up using....  I think I'm going to skip it next go around. The welds just weren't penetrating like they should. I ended up turning heat up enough to weld 1/4" steel to burn through the primer. Also, I bought one of those harbor freight pneumatic punch/flange tools. It only punches a 3/16" hole, did you use that size hole or did you drill it out larger? |

Here's what I used and we used just the holes made by the punch  |
