Something is up with Dragon's 1/72 kit tracks

Ok, i'm working on the problem, if i find a solution i'll post. THese tracks are highly detailed and look great. Except they are rejecting paint. After a week the paint is still tacky. I washed them in dishwashing liquid and scrubbed them with a old tooth brush. I used modelmasters enamel straight formthe bottle. I also tried Floquil strait formthe bottle also, still tacky, but not as bad. Still it leaves track marks on your fingers. I'll try aserious degreaser like simple green, and also try priming the tracks with a gray primer. Anyone else run into this problem? Bill
