We spent two days last weekend using Zep floor stripper to remove the old Redmax from our Class C.
We had put 5 coats on our 2004 Minnie back in 2010 while we lived up north of Albany, NY. It held up very well until we moved to North Carolina. Once the Minnie was out in the sun the Redmax turned the RV yellow.
For now we stripped off what was left of the Redmax and cleaned the rig well. I've purchased a good cover and hope to reapply the coating (now Zep) sometime before next winter. This time we'll be covering the Minnie until we get an RV shelter to keep the sun from it.
