I've welded hundreds of 1/4's...Are you using a used 1/4 or a replacement chineese one ?you dont have to go up the roof ether,Since youve never done this before (im asuming) do you think you can handle doing it like this????it'll save you a ton of useless work and be ten times better your fighting a loosing battle with a splice...and it'll be a very expensive lesson to learn. check this out. Full 1/4's I cut down the inside looks just as nice as the outside,the seam was steped (flanged ) for strengh and very little warpage,no bondo ,two thin coats of ez sand putty....ez,better,cheaper and faster.A used 1/4 is better than a after market panel and its still GM..pavetim said:I haven't welded it yet. I'm just getting everything to fit now. I'm gonna use 3m panel bond on most of it but the acutal splice I am gonna weld it. Well I just thought it was easier to splice. If I replaced the whole panel i'd have to take off my t top roof and it would come off in pieces and they are super expensive. It's a 1995 firebird. I can probably find a way to get in the back to paint it but i'm pretty sure I can't get back there to grind the weld down.
When I glue ,I use panel bond adheasive from SEM I use drill screws every 2-3" glue it and remove screws (when dry)glue up the dril screw holes real good....their like glue rivits (works very weLL) Was there a lot of damage? the inner structure might be bent up ..preventing a good fit...cheeck the door to 1/4 gap if its tighter than the other side you may need to do a little extra work,but check it first......used parts is the only way to go on most work ,for repair or collision...good choice :thumbup: :thumbup:is your panel bond made for steel? I've never used it ,some are for only fiberglass vettespavetim said:I got a quarter cut from a yard so it's OEM. I already cut it apart for my splicing so right now have to do it. If all else fails I can get anohter quarter and redo the whole thing. Ok i'll try the galvanizing stuff. Ok next question i've never used automix panel bond. I have some holes from drilling out the spot welds. Instead of welding the holes closed and grinding can I just "ooze" the panel bond out of the hole with I install my quarter and then sand the panel bond, and paint?
Thats what I thought too...I dont weld AND glue ...the extreme heat may damage the bond......I never believed you could glue a panel ,till it was demonstrated in front of me ...the glued seam was impossible to tear apart ... even with an air chisel...the metal tore before the bond gave up I resto'd a Ghia all the patch panels were glued & screwed ....10 yrs ago ..it still together ,looks good...I know it works first hand...very expensive though,not really worth the price any more..10 yrs ago/ yes ,it was worth it.cheaper than a welder though...35prog said:"OK next question i've never used automix panel bond.

There may be others that disagree, and they may get it to work, but my answer is no to the above process. If the hole is there, plug it shut. I would not see any need to use panel bond on a removed part. It is my experience, that it can only be used where seam is not an issue, jambs,tail lamp panel, outer wheelhouse etc. not on the sail panel or "body line" splice as shown by DB. That stuff works great for its intended use, and is garbage if it is abused.
