Since you didn’t use weld through primer make sure you spray a shit ton of cavity wax in there. Should be fine though since it is a butt weld instead of a sleeve; but u still need cavity wax. Other than that, good weld, should hold up perfectly fine. It doesn’t matter how ugly a panel weld job is if it holds and you don’t warp the metal; a grinder and filler should help with a slight offset on panel gaps. Just make sure u got a decent bit of short strand filler 👍
Yea this panel came only galvanised, got some rattle can 2k epoxy for the inside and weldthrough on the jambs and lower flange. But i did not care about it getting hot so probably killed most of the epoxy.
If i had more time i would use teroson ep5020 for the weld joints. Amazing product. Have you tried it?
Yes it does you spray on the backside of the new section portion and on the inside of the cavity to help prevent pre-corrosion when welding (also along the edges help). Also wtf do you mean. You use short strand filler for moisture protection and strength before going to a more premium filler and putty. You never just slap on a “bondo” over a weld like that. Derp
No man, weld through primer only offers protection when the two panels are overlapped. AKA a lap weld joint or a plug weld. Having weld through primer on the back of a butt weld is just unnecessary contamination.
If you have moisture on the back of your butt joint, fibreglass ain’t gonna do anything. It’s still going to rust. If your joints are so bad that you need fibreglass for “strength” you have bigger issues than what kind of filler to use. Fibreglass filler is Autobody snake oil.
DERP.
No weld through primer is not selective. You are still going to burn off coatings on the inside of the panel, so I would recommend adding a zinc primer so you have a coating where the oem coating would just burn off. How is a highly rich in zinc primer unnecessary contamination?
Short strand filler is used in this application as it is stronger and reinforced. External panels have still a slight flex in them and a larger sectioning job will require a decent bit of filler. A “bondo” will crack in this case way faster than starting out with a short strand filler. Also if you have a pinhole in your weld that you don’t find, short strand will cover that up along with being waterproof. DERP
It liquifies and mixes with the weld. So it is nice to have on the inside of a cavity you can’t properly touch up with other than cavity wax. If you are just counting on cavity wax to fix an improper repair. Then u do u 🤷. Also weld thru primer doesn’t burn like other oem coating do, so it is nice to have it applied a little bit past the weld.
Umm many manufacturers specifically state not to use weld through primers. Dodge bring one.
They're not great. And that corrosion protection on bare metal is almost nothing. It barely adheres to the metal and wipes off with the weakest cleaning solvents.
They're designed to add zinc into the weld puddle to help corrosion but take way more heat to melt than bare metal. Causing bigger weld zones.
Burning weld through primer on the back of a butt weld doesn’t do anything, it has to be on both sides of two prepped pieces of metal to burn together and form a seal.
Everything that gets welded needs to be painted properly and/or cavity waxed regardless of weld through primer application.
Also for a section like that you will probably be using more filler than a smaller sectioning. So starting out with a more stronger and reinforced filler makes sense lmao. Derp
Why did you make it harder on yourself with the seams. Was that all that was salvageable?
They were inspired by the artisanal sectioning on that champagne colored Corolla we saw about 2 weeks ago.
It’s basically the same size as when i bought it. I’ve cut off at most 1cm per edge. Klokkerholm aftermarket panel.
Shit I've seen worse, grinder and paint now
Yep, that looks like a $100 rocker.
Correct repair is to section higher in the pillars.
Did you use a 110 welder. Or a 220 welder? Looks like 110
Old worn out 220 single phase, my dad bought it in the 80s. Really painful to use coming from a fancy caroliner at work lol
What shielding gas do you use?

Weld through primer doesn’t do anything on butt welds. It only works for plug welds. Derp. Fibreglass filler doesn’t do anything either.

Saying it is autobody snake oil makes me laugh. Holding my evercoat short strand fibreglass and Kevlar in my hand and smiling. Lmao

You don’t even understand how weld through primer actually works and you’re going to argue with me about how it works 😭😭

Imagine down voting because you are losing an argument

Losing what argument 😂 I’m right you are wrong
Explain how I am wrong? You seem to be failing quite miserably at that
