Re: 1964 Arkansas Traveler Restoration
The key to body fillers is the fact that most people sand them too much....leaving them low. I leave mine a bit high, prime it, the block it out by hand. Just find a strait (thick) paint paddle, wrap some 80 or 120 wet or dry on it and wet sand it. Just use a light even pressure. Where you are high, the body filler will come through, where you are low the primer won't be scratched. If its really low you may have to fill it some more. I keep repeating till it feels good, if it feels good it will look good. If it feels rough, it will show.
On roughing out the filler, I would recommend getting a $20 8" or 10" automotive sanding block. They usually have a flat aluminum base with a foam back and a wood handle. They work great for working out the filler. Start with 36, then go to 80. Its better to build up the filler slowly, put on a thick glob and you will be sanding for the next 6 months! I actually use automotive filler on mine, but a lot of people like the marine fillers on here. Mines a trailer boat, so I went with the automotive. I figure each to his own, if mine was in the water all the time I would go with the marine filler. Same goes for me on the paints, I have had great luck with automotive products, but some people on here won't use anything but marine products....again I figure everyone has to weigh cost, use, expectations, etc and figure out what is best for them. Good luck with it and let us know if you have any questions. We give lots of advise and now warranties!
