I completely understand your concerns. Here is what I suggest, call or go to Sherwin Williams, and get the smallest containers for a solvent based clear coat, and a water based clear coat. Then in a inconspicuous location test each. If the solvent based attacks the paint, DO NOT USE. You still need to be very careful. The company that painted our driveway, 6-7 years ago with Xylene based paint (stain), stated they no longer do clear coating due to possible clouding of the clear coat. I have seen this reported several times before. I have no other advice at this time. We have decided based on the advice to not have driveway clear coated.
