what is the best way to fill in my side moulding holes on 65 chevelle,i thought about leading or welding them,if i do either,would'nt i have to
indent them first then weld or lead them,then use filler,like to have your ideas.thanks graemlins/clonk.gif

If you are good with a welder you can weld the holes shut, do not get to much heat to prevent warping and if necessary you may need a minimal amount of filler. This is how I did mine. Make sure you do not overheat the area you are working on!!! :eek:

Get a piece of 1/2 or 3/4 inch copper pipe and smash the end flat.Get a buddy to crawl in the trunk and hold the flat end of the copper tight to the body behind the hole.Then just weld em up. The weld wont stick to the copper and the copper will absorb most of the heat to help stop warpage. graemlins/thumbsup.gif

The copper trick work great. Make sure the weld zone and inside of hole are spotless. Remove any paint, primer from the surrounding metal around the hole. Take a drill bit to clean the inside of hole, any paint inside the hole can cause problems.
One thing I like to do is slighty roll the hole's edge this allows for more surface area for the weld to stick too so when you grind it flush you wont run the risk of grinding the weld too thin.
I take a tapered hole punch and a socket just a tad bigger then the hole.
Have a friend hold the socket on the backside of hole then very lightly tap the punch on the hole thus rolling the edge.
Once done use the copper as backing for welding.
Also NEVER EVER use water or air to cool the weld. Doing so actually warps the metal more. When you weld the HOT metal expands outward but can only expand so far due to the cooler, stiffer surrounding metal. because of that cooler metal the HOT expanding metal has no where to go, so in order for it to continue expanding it now starts to move upward and this upward movement is NOW compressing the metal or shrinking it.
If you apply cool water or air to that compressed metal you are only shocking the metal into staying into that compressed (shrunk) state, plus you are making it work harened meaning that it will be harder to work back to its original shape. So if you allow the metal to cool NATURALLY by its own means then you will lessen the amount of warpage in the panel as the metal will return to its former state, well most of it will. You will always have some warpage just cooling it will alter the amount...Eric
