Hi peeps, how did it go?? I am a body man and to me that would of been a way bigger hole by the time he had prepped the are for the new metalbum to go in. The only way to KILL rust is to, either cut it out an inch further back from the rust;or get it acid dipped/media blasted. Rust is a cancer of the metal.
The metal that is replaced should be a part of a new panel or sheet that has been elecroplated; not a sheet of bare tin!!!
This is because the sheet metal has been standing in a cold work shop exposed to the atmosphere. So your basically putting an infected part back in for it to breed..But this is probably me being anal ??.oh and Then Wax oil the s!@# out of it. Also zinc acid primer on the joins before welding as this helps to expel the oxygen from the weld too lower the risk of metal oxidation caused by the heat.
