lead work is the old school method and I think when restoring older cars it should be used....even if you are not powder coating .......its almost forgotten among newer body shops cause of the ease in plastic fillers......I think practice on some junk metal and get the hang of it.....just like welding, practice makes perfect.....I have tried the lead method...I am not near good enough yet to perform decent work but I am still practicing......good luck and go for it....like said earlier, got to start somewhere.......
