Faded Decals

They do make a graphic sheet adhesive dissolver. I can't recall the name, ATM. The dissolving liquid saves many hours of a machine in hand and the surface will be cleaner, when done.

for a 1999 motorhome i would expect the graphics to be pretty baked on the sides. you'll probably spend a good amount of money for someone to take them off for you or a good amount of time if you do it yourself. buy the 3M eraser wheel if you tackle this yourself. then you'll want to buff out the surface and possibly protect it before putting new graphics on.

check with your local RV dealers to find who they have fix theirs. Most cases they don't do it, but farm it out to someone local. Usually dealers will give you the business card.

I've had friends use one locally recomended by RV dealer. Did a great job.

I had the decals on my Class B redone by a local graphics/sign shop. He copied the shape of the old decals and printed copies as close to the original colour as he could. I had both sides and the rear done - all the swoops but not the manufacturer's decal. Looked great! I think the total cost of removal and reinstall was around $500. Not bad.

Mobil sign shops do it. When I have one side done a few years ago I found a guy thaat had a truck that came to me and did the job. Not cheap for sure. You might consider stripping the old decals and painting new ones on. Most auto paint stores will fill rattle cans of any color for you pretty cheap.

It is not an easy job. It takes patience, a heat gun or hair dryer, plastic scraper & something like naptha to clean the glue residue off. Did I mention that it takes a long time. Keep that in mind if thinking about having somebody do the job.
