Body Fillers

I just put new rear quaters from AMD on my 70 swinger. Now it is time to decide what filler I should use to fill in the area from the quater fender to the roof. Some people say short strand kitty hair from evercoat is good or metal to matal from evercoat or USC. Any suggestions. Thanks Ken

I've used both types with good success. I think it depends on personal preference. If you haven't used metal-to-metal it might take a mix or 2 to get the feel of the correct filler/hardner mixture since the hardner is liquid.
