sorry this took so long...i got laid off and was ill for some time. as for the few folks who thought this was a worthy project: YES! yellow rit dye and a small amt of red rit dye added to hunting clothing will knock the uv out. i used about 5 teaspoons yellow to 1 teaspoon Red per load. then i ran them thru using the new rit dye fixative. NO...I don't know how to post pics, but yes it does work...as long as you don't rewash the clothes using petroleum based detergents with uv enhancers(and yuck!...fragrances). so there it is. hope it helps. for those of you who thought this was a joke, pls pass on the flaming. If you are THAT good that you don't need uv killer and can hunt wearing mennen aftershave and still take a p&y buck every year, more power to you!
