Could use some help...
There is not much difference between repairing a steel body car versus that of a fiberglass car. Each have their "pro's" and "con's"...BUT...the basic principles are still the same. PROPER PREPARATION!!! Procedures are different...due to being a steel body...such as welding, brazing, leading, and pulling dents out, etc. The difference lies in making sure that you TRY to reduce/stop any growth of rust....while on a fiberglass bodied car...you have to worry about cracks, seam separations and panel distortions.
RUST is your enemy on a metal bodied car!!!!

Dub, before I saw this thread, I saw your PM! I was replying (about 5 paragraphs) when I lost it...wtf!
I hate it when that happens, LOLI have not been in the painting section for quite some time now...when I painted the LT-1 4 years ago, there was no painting section...needless to say, sure wish you guys were around then. If you care...search my history... you'll see the project unflold.
Since then, I've painted a 1948 Mercury sailboat (wood), sold that and picked up a Santana 22 in which we just completed. The latter was shot with Awlgrip. You may know the product.
Regarding the thread... last week, trailering the Santana home... I managed to crunch my 08 Tacoma tailgate...wtf!! Anyway, I hammered and doll'ied for a couple of days (gently) very thin!!
The problem was and somewhat still is... I have some swelling due to the hit (it was buckled pretty good).Last night I googled and came up with heat! Here we go...got the gas ax out...
and with some success managed to pull the strech out..but, also managed to distort to some degree. Dolly & hammered some more...looks pretty good. Well, not bad anyway. This afternoon, I took some Evercoat and found some more high's
Q. Can I tap these highs with the existing EverCoat in place?Thanks heaps for your time and consideration!!

When you were heating the panel with the gas ax...did you by chance apply water to these areas to shrink it back...and thus strengthening the panel again...and not make it so flimsy. I don't think that the tailgate is made out of HSLA steel...which should not be heated with a torch. A torch can make HSLA steel brittle. And usually HSLA is used in frame rails and "crash" areas of the car....but you never know.
Seems like you about have it completed...but I was just wondering if the panel could "pop" in and out on you...which is usually a sign of stretched metal.
YEAH...the steel on new vehicles is so weak..you can blow on it and make a dent. Hard to get back right due to the thin gauge of steel....unlike that of the steel on a 55-57 Chevy. I applaud you for spending the time to fix it.

Dub...yes I did use water immediately after heating up quater size spots on the pannel.... I could see the shrinkage as I did so...
There was a point...that the pannel was popping on me...it would pop in...and leave a nice 6 inch divot...WTF! Thought I lost the tailgate, but, after heating up again...what I thought was an area that was causing this pop...it remedied the pop...and seems strong. No popping even if I smack it pretty hard... I'm sure once I weld back the rear re-inforcing..she''' be good! I'll get back into it..with in the next couple of days...and post up some pic's...thanks heaps

Q. Should I seal the tailgate? If so, should I seal it at this point, or on top of the Dupont high build?? B/C, C/C will be Dupont too...
Thanks in advance!!

It is a pigmented sealer and it is Dupont... I'll go get the part number (sealer) and check Duponts web site, tech sheet. Have a great evening!

I'll attempt to describe...I had the tailgate down for a better visual while I was backing up the Santana 22 (sailboat) trailer. I had to jack knife this trailer into position and caught the ladder of the trailer head on with the tailgate in it's horizonal position. The result was, top of tailgate, just off middle was bent towards the hinges approx 2 inches
. Catching it right in the middle of the top edge... bowed the outside and inside out approx. 4 inchesin both directions. Needless to say, had a lot of creasing going on...in all directions
Lots of streach
I removed the tailgate linner, then cut 4 sections out of the inside tailgate to gain access to the outside pannel. From their I hammered and dollied...to the point where I had to heat up the pannel, numerious times, hit with cold water rag so as to shrink the pannel. I found this technique on the internet
From their I only had to use very min. bondoI then removed all the paint on the outside of the pannel, scuffed the jams, shot BC/CC the color sanded.
Not bad for a first time metal worker, LOL
Thanks Dub and members for your help
