looking for the easiest method to remove original grahics (decals)from fiberglass rv. currently using the hairdryer/blade method. very time consuming with low productivity
A few years back, I removed all the decals from our 04 Sandpiper fifthwheel then repainted the design back on. I found that using my daughters wallpaper steamer made short work of most of them.
If you use a heat gun, keep the heat low and use it just long enough to soften the decal. Too much heat can affect the glue used in the construction process and lead to the sidewall becoming delaminated. A hair dryer works the best, and is the safest for decal removal. It is not an easy process but they can be removed, usually in pieces.
I did the heat gun method on one side of the coach a few years back. It was a job. Took several days. Started the other side yesterday with a WHEEL. Much easier, cleaner and quicker.
Depending on the age of the stickers heating them might not be viable.
I had some very stubborn stickers the body panel covers at my fuel tanks (under my doors) - i was able to remove SOME of the sticker but the glue remained behind, no amount of goo gone or aero paint prep would touch the glue.
a few minute w/ the Eraser Wheel in an electric drill and the glue was gone & the paint looking like new !
Heat gun and sharpened credit card. (Drag a old credit card through one of those "V" shaped or a multi disc sharpeners) Less chance to scratch the paint/gel. I see Amazon has plastic single edge razor blades now.
