ASP is a soak off gel polish that's quite watery. It took three coats before I was happy with the color. After applying the third coat, I applied the Deborah Lippmann glitter polish then cured it under the light. You can always use any kind of regular nail polish over the gel before curing it. Usually many people wipe the sticky coating off the gel before applying any kind of regular polish but it's really not necessary.
Once you're satisfied with the glitter coating or whatever regular coating you're applying over the gel, it must be cured under the UV light. You can apply a second coating or other designs and re-cure, or you can go ahead and apply your gel top coat and re-cure as normal. I've seen some gel nail designs where the nails were coated with gel polish, then designs were drawn on with regular nail polish. All you have to do is wipe the sticky coating off the gel polish after curing it. I'm learning how to do designs practicing on tips. I've even did a water marble design over the gel polish which turned out pretty nice.
