I recently bought some Pattos peel and stick decals to put on Lexan HO NASCAR type bodies. They are high quality with sharp printing. In my case the decals were not quite the right size. I chose 1/64th scale, and those decals would have been a perfect fit on a 1/64th scale diecast body, but HO cars are seldom in perfect 1/64th scale. I had to cut up the decals and make the pieces fit together. I could have asked for a custom size, like 1/72nd, that would have worked better.
The peel and stick decals are thicker than waterslide decals, they should hold up to some abuse without needing a clear coat, but a clear coat might help to hide the edges of the decals.
I used peel and stick decals on 1/24th and 1/32nd scale cars in the past and had little trouble positioning them, with HO cars that is more difficult. It helps to put soapy water on both the body and the decal before you lay it down.
