a little experience.
Having done this a couple of times I have tried different methods.I tried to remove the original stripes on the cabin with a hair dryer, heat gun, razor blade and they would not budge. That is when I found the Eraser (Photos posted in the photo forum). These stripes were very thin and brittle. The eraser virtually melted the vinyl stripes off. The entire job was done is less than one hour.The next job was to remove the painted on name off the stern of the 'Heather Marie'. No question about the quick way here, just use oven off that does not need to be heated and off comes the stuff. It is best to do this on a nice warm day (stuff works better and quicker). Once it gets most of the paint off, you can use some polish, or Island Girl to clean up and treat the gel coat before applying the vinyl or repainting.The next process was the vinyl stripes below the toe rail. This was not nearly as easy to remove with the Eraser. This vinyl was still in good condition on most of the boat. It took about 3 hours to do one side. I am thinking that it may be worth trying a combiniation of heat and/or chemicals with the Eraser.The importance here is what works for the conditions that you are working with. The material that you are removing and the working conditions will influence how well the process will ultimately work.
