Using lead to fill trim holes

I bought the kit from Eastwood and think I am going to use the lead on the top side where I can be sure it will stick. Leaning toward bondo on the quarters, fenders, doors. And yes, using a propane torch has been a challenge getting the heat right. Good thing I went for an extra couple of sticks of lead just in case. And FYI, my dog had a good time trying to eat the wax that comes with the kit, Keep it somewhere safe or you will be picking dirt and grass out of it once you get it off the lawn.
