Outside RV finish?
Another good cleaner is called "Bellywash", available fron several places on the internet. We use it for what it was designed for, to be used to clean the underside of an aircraft fuselage. It does a really nice job of cleaning whatever, including hydrocarbon residue, as well as tar and trash from taxiways and runways without harming painted and alumnum surfaces and decals (if you are careful), so it will also work well on RV's and Motorhomes.
Also, for those of you who may/may not have heard of either Nyalic(.com) or Vivilon(.com). They are 2 very similiar polymer
clearcoat products that do a REALLY nice job or restoring color to an old faded or oxidized painted finish WITHOUT having to repaint (ever again), and are AWESOME as a VERY hard easy to maintain clearcoat over an already nice finish that you should NEVER have to repaint after coating.
There are before/after photos on either website that accurately depict what these coatings will REALLY do.
For those of you who plan to go the the RV Show in Atlanta next week, Feb 17th or so I think, I will be hanging around there, and should have a vehicle that has the clearcoat on it. If you will email me at
patrick@hmsga.com I will email you with a contact tel # so we can arrange to meet and I will show you an actual surface that was coated with this type product.
