This is my 3rd season dealing with the boot stripe on my 1985 H31. Three years ago my wife decided she would make a present to me of repainting the boot stripe for me. She and her sister tackled the job in secret and they did very little preparation to the old surface. In fact, all they did was wipe it down with a spray cleaner like 409. From there they taped it off and applied two coats of Interlux Brightside. To compound the problem, they applied the coats with the temperature hovering in the low 50’s and it was rained on while still tacky. The paint they brushed on has been peeling off ever since, and each season, I’ve been touching it up, hoping it was only a few affected spots.. This year while I was washing the hull, large portions of the stripe flaked off from the pressure of the water stream coming out of the hose. This was not any type of high pressure system, just a standard garden hose. When I went a step further and started scraping the paint with a razor, it flaked off the old finish far too easily. I’m not exactly sure what the old finish is, possibly colored gelcoat, but the separation between the new and old surfaces was very pronounced. I have resigned myself to removing all the new paint it with a razor and sanding out the old finish with my rotary sander using 220 grit, wiping down with acetone, and re-applying the paint. Although I’d love to use vinyl tape, I can’t because the stripe changes width as it runs down the side of the boat and comes to an oval like area toward the stern. I have read the archives and can’t find a similar issue with a boot stripe peeling like this. I am convinced it was a problem with the preparation. Live and learn, I guess. If I had done the job myself I would have only wiped down the old stripe with a solvent. I do not think that would have been enough however, and would recommend to anyone contemplating this job to sand the stripe . I decided to write this post to warn others not to scrimp on the prep tasks with this seemingly simple job. In spite of my wife’s good intentions, I have put far more work into this than I would have by doing it correctly the first time. Still I consider myself lucky to have a woman who would undertake such a job for me, regardless of how it turned out. I’ll be sure to report back to let you know it all ends. Sympathy and comments are welcome.

if you don't have one, rent a 3000 psi pressure washer and blast the 'new' paint off first. Then sand with 400 wet or dry and then 600 or 800, both wet. Then clean with acetone on a rag(carefully and lightly as it can soften the surface) and then thinners. Then mask, following the origianl contours and using a razor blade to shape the tape to the contour. Finally, paint. Good luck and yes, you are blessed to have an admiral who is willing to take on grunt work! How will you show your appreciation?

Answers to your questions
Rich L: I'm pretty much locked into Interlux Brightside sapphire blue, since I used it to replace the upper tape stripe as well. It is an Interlux recomended paint for boot stripe work (one part polyurathane). In fact, Interlux markets some Brightside colors in 1/2 pint cans specifically for boot stripe applications. I'm brushing. Rolling is a possibility, but its only a 4"-5" stripe. Spraying is beyond my capabilities. I can live with the brush marks. LaRue: I took off as much paint as I could using a water hose. A pressure washer would have probably gotten more off. Following that I used a razor scraper and scraped off the reamining paint. It came off very easy. Too easy. Then I sanded the entire stripe with 220 grit paper using a rotary sander,(sorry Chris, 220 is what Interlux reccomends in their application instructions). Finally I wiped down the surface with Acetone until the residue being picked up on the rag was nearly nothing. Last evening I taped it off and brushed on the first coat. So far so good. Dont be afraid to thin the Brightsides. I used regular paint thinner (not the $18/can "special thinner") and it worked just fine. I plan to sand out any runs and recoat in a day or two. Time will tell if the paint stays in place this time.

Thanks so much for answering all my questions. I have two boat's to deal with one with stripes that I will work on this weekend and the other one next week with the paint. I ordered factory stipes from Hunter, paint I'm getting at the boat store that has the boat on the hard...the problems were getting the old stuff off.... Katie 28.5 Hunter La Rue

paint color
Paul, Super. Just one last quick question... where does one view the colors of Brightside paint? I've scoured the web and can't find a color chart that enables me to choose a very dark Hunter blue to match my current boot stripe and sail covers. Many thanks! Rich

Rich: You need to scour harder...
go here.... http://www.yachtpaint.com/usa/ and click on product guide, and then paint finishes, and then brightside...click on the image of a brightside can and you'll get the brightside product details page. There is a option in the table to look at a color chart. That being said, be careful matching colors over the net...West Marine sells the stuff. The can tops are sample coated so you can get a real look at the real color.
