Ty, It looks to me like you just need some more practice welding. Spot the holes untill they are gone. Bob

Yeah i cant weld sheet metal worth **** but am trying.

should i put a piece of copper behind what im welding to be able to puddle the weld and displace some heat? trying to get this done so i can prime something tat i actually sort of know how to do.

thanks for the help.

I think you would have been better off putting the whole panel on. Don't you just love Champion socks? I do. I'm wearing Nike socks now, they are much thinner and they don't last nearly as long as the Champions do.

I use a alum plate because it will not leave anything behind like brass or copper will.

You should in the future try to overlap the patch by 1/4" so it will not blow thru so easy at least until you become better at welding. Also it is better to cut the corners rounded rather than sharp 90 degree seems to keep heat down and warp less. Since you already have the holes you should either make tiny patches or just quick spot welds on the edge of holes until you get it sealed up. A tig is better suited for patch repair.

You had a complete panel and by the look of the rest of the old quarter you should have replace it completely or at least the bad half. There is previous body work looks like either a bad dent or bad rust from before. I hope you'll seek more advice before hacking up more brand new replacement panels.

Your doing just fine... don't let it get ya down.

Trigger you welder with fast bursts giving time in between for cooling and let the holes fill a little at a time.

Put your boots back on!

if I cant do a small patch panel properly how do you thnik a while 1/4skin replacment would of turned out?

If i knew what i was doing or had someone to help me i would do the whole 1/4 skin replacment but the rest of it is pretty fine expect for that some areas that I will be able to hammer and dolly out I did what i thought I might be able to accomplish.


thanks for the advice, gonna try and fix it tonight and then I will post up some pictures.

When you are ready to use body filler do a first coat with the filler that has fiberglass strands and is water proof. This way if you have a hole you did not see the filler will seal it. "Kitty hair" will stop moisture from contacting your body filler and bubbling the paint later.

Fillers can absorb moisture and create a problem so it is best to protect the filler from moisture.

replacing the 1/4 skin isn't as hard as you think. Mostly just more time involved in cutting the old off and prepping it for the new. You would actually have less welding to do if you get it right and spot weld it on the flanges. Hey atleast your giving it a shot.

well I realized by the time if I fix it its gonna be a piece of **** so im seeking help. My dads friend owns a body shop but they dont like doing resto work but has guys that are willing to do it on the side. So when my dad plays golf with him hes gonna talk to him about it and see if he can get a guy over to check it out and hopefully do new 1/4 skins or whatever he thinks would fix the problem the best. Hopefully he could do it out of my garage because I am not able to move it at the time with out having to go buy rims and tires which im trying to avoid for a little while. Trying to get this damn thing ready for bondo and primer.


Thanks for all the help.


Ty

Why not just finish what you started? You had a plan so go through with it. Even if you don't end up with the brand new quarter a pro would have done you'll still have something better than it was. If it fails and rusts in a few years just redo it properly. You will be better just getting it finished unless this is a show and not a daily driver.
