RE: [Chrysler300] 64 Quarter panel project





Ryan -
 
I follow a practice similar to yours. If I was welding a rocker panel, I would spray the inside of the rocker with cold galvanizing compound. Once it dried, I would wire wheel about an inch or more of the area where I will be welding the panel in place. The metal needs to be completely clean in order to produce a successful weld. Nothing gets flanged, except if it was done that way at the factory. Everything is butt-welded.

Interesting comment Ron. In an effort to try to protect metals that will not be completely accessible after installing a panel I have often used zinc primers prior to welding. Despite the inference that one can "weld through" these primers, I never liked doing it for the reasons you pointed out...I suspected it was problematic. Once I secure the new panel I found it best to then clean off the primer where I'm laying down the weld, hoping to both protect the bare metal and have a successful weld. 


For instance, joining an extension panel to the lower edge of a quarter panel. I would punch holes in the quarter and plug weld them to replicate a spot weld. To protect the back of the steel on the two metal panels I would prime them on the inside with zinc (weld thru) primer. To leave a clean welding surface I would mark and remove the primer where the weld was going to be placed (with a mig welder) 


How do you go about protecting the inside of the panels in this type of situation?

Weld-thru primers should only be used after-the-fact. The zinc in these primers (aka cold galvanizing compounds) will contaminate the weld and virtually ensure a failure. As a bonus, the burning zinc is toxic to breathe.

There are places where flanging makes sense and is an acceptable method. My experience with flanging body panels on a car is that it leaves a beautiful spot for corrosion to take hold and doesn't allow you to properly dolly the panel when needed. Using weld through primers can help with the corrosion aspect to a point but it's really not a good method for joining panels in my opinion. Also if I were to flange a full quarter panel, I think I would want to use a bead roller so I could better control the depth of the flange.

Sorry, but that video is nonsense. When I butt weld, I leave a gap the size of a nickel between the two panels. Then you get the penetration so that when you grind the top welds smooth the weld underneath, as well as the metal that has now filled the gap, holds the panels together. I then light-test the welds and fill any gaps with a weld bead. I've never used a flanging tool for sheet metal sectioning and I've been doing thin gauge sheet metal sectioning on cars for over 25 years. Eastwood does sell some quality products. But they tend to be expensive. You can source them cheaper if you look.
 
Read Mike Milligan's remark in the Comments Section below the video on You Tube.

Dave...Happy New Year   !!!

While I do work at Eastwood I am not an expert, not even a novice, at what you are doing. Perhaps you should follow Mike's advice.

Whichever way you are going to do this I would strongly suggest calling Eastwood for their advice and suggestions. They have the best customer service and tech support and I am not just saying this because I work there. When you call ask to speak to Matt Murray.
Also Eastwood has lots of videos that you can find online. Check out this video. This might be a better way than using a panel flanger . I would still get Matt's opinion  on the best procedure.

Bye and have a great day.

Hello Members,

I finally found time and tools to remove quarter panel skin from semi frame up to door jamb.

This is a big section of 300, spot weld cutters and abrasive cutting wheels are engaged.

I should have outer skin and trunk extension removed, in one piece, with more than enough steel left.

I will be using Eastwood flanger tools. My big question is.. when ready to cut into the vehicle, a long seam will exist.

Does the car section get flanged, or does the donor skin get flanged.

I intend to cut into the 300 after the Spring meet. should be interesting, having straight panels with tight fitting trim.

Any tips or experience will be accepted.

Thanks all,

Dave in Va.
