They are surfaced mounted, unlike the main waterline stripe which is imbedded. Iwas planning on the hair dryer, heat gun approach, thanks for the reinforcement. Big concern is always to not damage/burn the gelcoat.I have a 2004 Bene323 and I honestly cannot remember whether the stripes are in the gelcoat or simply vinyl stripes. If they are vinyl striping, they should peel off relatively easily using a hair dryer and a plastic putty knife. Wipe the surface with acetone before putting on the new stripe. You could also use a heat gun, but that can be too hot. Do it when the heat of the sun can help out. The new double stripe can probably be purchased in rolls from an auto body supply store.
If the stripes are in the gelcoat, forget it.
Thanks for the input. Never a fun job. I did it on a 80's vintage Hunter with good success and was interested to seee if anyone had an alternate method. Looks like heat and patience are still the key.moderate heat from a heat gun..... (be careful!). It will loosen it up and release it so you can either just pull as you heat or use a tool to scrape it off. Did it on old boats and will be doing it on my new to me 2005 423.
Good Luck!
There are mechanical devices that do a great job, just do a Google search on "vinyl stripe eraser." Basically just a rotating wheel that attaches to a drill. I used to have a 1988 Hunter and the boatyard used this method to quickly and easily remove the fading/peeling stripes from it.
Thanks John, hadn’t heard of that, will check it out.
