You can get the gallon in the Zep line if you wish to use that striper.
We only had flaking in a couple places. One was on the front bumper and the other the top edge of each cap but they ever small in size.
We just washed the MH well and when over the spots a few times before we recoated with a couple of new coats over all of the old RMP/Zep.
Never plan to strip for a few few spots that I would have to look for them to find them today.
RMP/ZEP is to protect the skin with a nice acrylic plastic clear coating. Runs, spots, etc non issues if protection is the main objective. :B
