RA,
I'm not familiar with the bright sights stuff, but I am an experienced paint guy. Obviously we have an adhesion problem causing the paint to not stick where it's supposed to. This can be caused by a couple of things. First, the surface may be improperly prepared . This can be caused by the recomended cleaning agents leaving a "non stick" residue, or the surface actually needs to be "roughened" up a little to give the paint ridges and valleys to stick to. Second, the paint is not being allowed to cure long enough before another coat is applied. From your comments and Bullrock's I suspect this may be the issue, despite what the mfr. says about drying to tacky. Third, the paint you have is just plain not going to stick to your application without a primer and maybe some surface prep. My instinct, based on what you said is to try this: remove all previous paint and clean via mfr's instructions. Then, wipe dry with a tack free cloth and wait a good long while for any solvents to evaporate, or apply light heat (eg. hairdryer on low and indirect) . Paint lighter than recommended, then give it waaaay longer to dry than the directions say, or apply light heat (eg. hairdryer on low and indirect) to speed it a bit. Check results, and apply light additional coat with long dry time as above. This should get you something better than a sticky gummy bear paint sample. My experience with most paint suppliers is that they are tuned into the gotta have it now needs of paint consumers, but the products don't dry nearly as fast as they say they will. Best of luck
