Depends if you are planning single stage or base coat clear coat,the 2nd can be very pricey single stage will run $200 per gal aprox including reducer and hardener.
You will need a good primer also so that you achieve a good bond you can usually get a couple qaurts for around $100 including hardener,you will need lots of wet/dry sand paper also 400 grit up to 1600 grit this is fairly cheap.
Do a search on MUD for your paint code number I believe there is two shades of Dune.
I have a gallon of ppg beige that I decided not to use. I "thought" I was buying the dune beige, but it's actually the beige that went on the late model 40's which has more tan in it than green. It's their shopline level, so not super expensive. Not sure if you can ship paint like that or not....
Sand paper? I spent aprox $200 also (single stage dune beige) . I wasn't getting to picky and just shot it and called it done. Actually turned out better than expected. Got at carquest , brand ? its at my shop.
