I was able to remove the stripe tapes on one side of the boat, took over 6 hours! The blue was not too bad, but the silver/grey took almost 4 hours alone.

Now trying to remove the stripe adhesive from the hull.

It's like the glue from hell!

Goof Off - Doesn't touch it.
Acetone - Ditto
Oxalic Acid, only cleaned the fiberglass, didn't affect the glue at all.
Soap & Water, Na! Nothing doing there either!

Rubbed it with thumb as suggested elsewhere, I swear that it laughed at me.

Getting ready to take an angle grinder to it! Grrrrrrr!

Help!

Reminds me of removing silicone (gobs and gobs of it) from the aluminum window frames. Oops would only soften the surface.

I can sympathize!

This probably won't do very well for very old adhesive, but I generally find the best way to remove tape adhesive is with the very same tape--simply "blotting" the residue with the sticky side of the tape. Little by little, the residue lifts off (usually).

Made some progress. I had not realized that Goof Off had some effect upon the residue.

After several soaks with Goof Off and using a Plastic Scraper meant for bedding FG Resin, I was able to strip it off.

Very messy, had to soak a fresh cloth and wash it down multiple times to remove the final traces.

There is still a visible ghost of the location, I hope when I polish the hull tomorrow that disappears.

The new stripe does not match the old. It is a thick stripe and a thinner stripe in the same blue, so the ghost will show if not removed.

Should I use Ghost off

I ended up using a heat gun to get the graphics off of SL, which was reasonably effective. It sounds like you figured out the best way to use Goof Off, we've learned to just let it soak for a while as you did, and you get decent results. Last time we painted the boat, we left the masking tape on for too long and had to clean up the tape line. Goof Off worked, but it took a long time and a fair amount of elbow grease.

Time usually cures the ghost. Clean off all color and residue and a season of UV will probably invisible.

No one will notice the ghost.

Do you plan to re-stripe, or leave the boat plain white?

How about navy blue Awlgrip over the whole hull?

We purchased new stripes from CD. I'm about ready to apply it to the port side.

Looking for best method of application and keeping it level.

Did this last spring. I used wife's hair dryer and razor blade. it took about 1 hour after trying all kinds of removers. Just be careful to not shave the gelcoat. Slow and easy and it comes right off. Also when applying new stripe I marked the hull with a pencil and applied the tape in 3 -4 ft. sections rather than an inch at a time. Don't stretch the tape!

Ever done tint or auto graphics? I'm betting you can soak the hull with some dilluted dishwasher soap and apply the stripes all at once and move it into position. Once positioned, squeegee out the soapy solution. A heat gun will shrink the graphic to form around rounded areas.

Thanks for that tip Johnathon.

After my first screw up with wobbly striping that I pulled off in disgust, I used this method to replace the stripes on the port side (stbd side can wait till we get back from our next trip.)

Once the stripe was removed, I cleaned the hull with Goof off and soap and water, then several rinses to remove any residue.

The stripe material has 3 layers.
Layer 1 is a backing tape. This has to be removed as the stripe is applied to the hull.
Layer 2 is the actual stripe material. Ours is dual stripes, the top is about an inch, the lower is about 1/4"
Layer 3 is the paper that is left on until the stripes are correctly positioned on the hull.

Next I used 1" painters masking tape to strike the line. It took a couple of attempts, looking along the line made it easy to detect if I had wobbled.

Then I asked Peggy to assist as it really is a two person job.
Peggy sprayed the area above the masking tape and held the roll of new stripe as I removed the backing tape(layer 1) and applied the tape. The very mild soap spray did allow me to re-position the stripe tape without it peeling off from layer 3.

Then when it was finally positioned with the bottom of the outer (top) paper still covering the stripes, I used a squeegee to remove any bubbles and ensure the stripes were fully in contact with the hull.

After trimming the ends of the stripes and layer 3 to match the original stripe ends, I removed the layer 3 paper, keeping the paper flat against the hull so as not to tempt the stripes to peel off the hull.

Lastly, I removed the masking tape.

Looks great! Now I have to allow the adhesive to cure and polish over the stripes. Before I do that, I'll apply the new boat lettering and the new Catalina 250 logo.

It took all of 20 minutes to put the new stripes on one side. Very pleased with the results, now it's obvious that we need to repeat the process on the stbd side.

Thanks for your help folks.

No prob. Glad it worked out. Can't wait for pics. My red stripes are super dull. If they dopn't brighten up after a good wax, then I may apply some new ones.
