Do any of you girls have Acrylic Gel Nails?

Any Nail Techs out there? I just had a full set put on a couple of days ago! I just wanted to know if you know, if it would mess up the nails in any way, if you put Clear Topcoat on top of the Gel Nails, to freshen up the shine, if the shine begins to get a little dull or if it's ok to do that! Thanks!
