I clay bar 3 vehicles about every other year. When you can feel roughness in the finish after a wash and wax. Can't imagine doing my 5th wheel without having my arms fall off. IMO just don't need my trailer finish as nice as my vehicles.
Also need to realise it's taking your wax off too so you need a couple coats to get the protection back up to snuff.
