You mean Brush lips like this?
If you had Polish lips before then most likely you wont have clearcoat over the lips unless asked for when buying. Its hard work since you have polished effect on there and yes very good idea to clearcoat afterwards. IF your willing to send over your wheels I can pm you a friend that does painting and can do Brush.
You can always try it over the weekend and have a painter clear cooat for you just like a painted service
Hope this helps
