Hi. I'm doing a 74 Super Beetle restoration. Can you tell me what primer, sealant, and rubber undercoat you used? Many Thanks.

[@AircooledProject]

Hello. The 2k epoxy primer and 2k polyurethane paint are from a romanian manufacturer called Romtehnochim. The undercoating and seam sealer are from Foerch, products L260 and K126. The layers, in order, are: primer x2, seam sealer, undercoat, paint x2. Good luck with your bug!

[@BigBerk765]

So I have a question for you, if you don't mind.
When you weld together sheet metal, like a floor, rocker or body panel, I know you grind down the outer edges for a smooth clean look. But just like the outer side, do you also smooth out the inner side, too? So the panel looks smooth and clean on both sides? I've always wondered that. I'd assume that both sides of the panel would smoothed over inside and out.

[@AircooledProject]

Hello Taylor. The floors are spot welded. When spot welding sheet metal, the sides that overlap should be cleaned down to bare metal and treated with zinc primer. Also, after welding and epoxy primer, seam sealer should be applied on both edges of the weld, so water can't get in between the sheets of metal. If you are asking about the butt welded panels, the goal here is to leave a small gap and fill it with weld(if mig welding). You don't need to grind down the inner side if it's not visible. Applying some primer and seam sealer over it shoild be enough. Maybe you would grind it down if doing a showcar or something like that.

[@BigBerk765]

@@AircooledProject Ah, OK. Interesting. But if someone wanted to, they could smooth out the inner side of the weld just as much as they’d do the outer side, right? If you were doing a full concourse style rotisserie restoration or something of the sort.

[@AircooledProject]

Yes, of course, if there's access on the inner side. Some areas are closed. In this case, the right way to do it is to replace the whole panel that is usually spot welded.

[@BigBerk765]

@@AircooledProject Super cool! I’ve always wanted to learn more sheet metal welding and that’s some awesome stuff! I’ve got a vintage luxury car that I wanna restore and make absolutely perfect for a show car; a 1977 Lincoln Continental Town Coupe. Granted, it’s MUCH bigger than that Beetle, but it’s one of my favorite automobiles in the world. I wanna do my baby right, so I wanna learn as much about professional automotive restoration as possible.

[@AircooledProject]

That's a very nice car. Good luck with your restoration!

[@keithmarshall8920]

Hi There. Can I ask what type of weld you are using for those spot and patch welds please? As in Electrode Arc, Mig or Tig? Thanks

[@AircooledProject]

Hi Keith. I used a stick welder with 1.6 mm rods for the most part, because that's what I had in the beginning. Then I got a MIG welder, so I used that to weld in the floors. MIG is definitely the way to go. 0.8mm wire with gas shielding (argon and co2 mix).

[@tospicy4ya]

Was that weld through primer at the beginning?

[@AircooledProject]

Yes, zinc based. Cooper based would be a better choice. Didn't know aboit it when I filmed this.

[@sacramentoreps]

Can anyone tell me what is the name of tool that making holes?

[@AircooledProject]

Google "pneumatic hole puncher"
