tWax yes but opticoat not, Xpel has a self healing feature due to "soft" top however coating this top layer will but a hard layer on top of it, our detailers in The Netherlands strongly advice not to do a coating on top of the Xpel.
This makes sense to me based upon the healing properties. I will have to ask the folks at Xpel. I wrote to Griot's a while ago and they make no product for coating Xpel and appear to have very few requests for such.
