it's shiny appearance lasts MAYBE 5 years IF you put covers on your bumpers and NEVER EVER hit a dock.Repairs CAN'T be feathered in to disappear
Stick with gelcoat..... It came on the boat and lasted 20 to 30 years ....sand the boat and regelcoat it.....it'll last another 20 or 30 years
Ok, interesting info. Thanks.

Gel coat comes with it's own built-in color (can have color codes, etc.), created by mixing pigment into the wet slurry that becomes the hard gel coat layer.

The fiberglass itself is usually mats or strips of "fabric" made of loosely woven 'glass strands, and the 'glass matting is then infused (in a number of ways) with resin. Once all that hardens, the hull can come out of the mold for installation of systems, deck, etc. (There are several technical methods of creating a fiberglass hull, so this is just a quick-and-dirty.)

Some makers add an additional layer of gel coat on the inner side of the hull, partly for cosmetics, partly to make cleaning etc. easier.

Paint isn't necessary over the top of gel coat, although some makers do that for cosmetic purposes (e.g., to change the hull color topsides), or sometimes as a "barrier coat" to help the gel coat further resist water intrusion (bottom, under the biocide bottom paint).

Gel coat can be repaired, although sometimes color matching can be an issue; even with manufacturer's color codes, the rest of the gel coat around the area to be repaired may have faded over the years. I've read some paints are easily repairable (AlexSeal?), some not so much (Awlgrip?) in small patches. No first-hand experience.

Are these epoxy paints awlgrip and the others a new paint system? or have they been around for a while?

20+ years. I tried the more expensive plant but found them hard to repair and match. The same with gel coat. Even the white. On the Eagle for the last 10+ years been using Interlux polyurathane which lasts about as long but easier to apply and match. Ever year it seen I come in a little to hard and mar scratch gouge the paint. Which upset me but not near as much as the paint was expensive epoxy and or gel coat.

This year painting the Portuguese bridge and the port side and stern. Should finish over the fourth. Since the base is good just alight sand some primer and new top coat. Cost about two hundred bucks and my time. Anyway I would not want an expensive epoxy paint job.

when planning to build the steel cat i read an interesting piece on the materials you could build a boat from, and the short and long term cost and how much you would save. thou the upfront cost is very high, the long term, 40+ year cost is much less, but i was just being wise.

Years and years.

FWIW, we had our "dashboard" re-glassed -- and re-gel coated -- when we updated our electronics suite a few years ago, and the change isn't visible from more than about 3" away. Even then, you'd have to know it was done, and where, in order to see the slight differences. Subsequent sunlight is making the match even closer.

As I said, I don't have any experience with the various paints, although other folks I know have said AlexSeal is easily repairable and Awlgrip isn't. I think there's another brand (or maybe more) out there, too, but can't think of names just now. Their manufacturers' websites would likely highlight desirable features (like repairability)...

Re: Fiberglass maintenance?

GelCoat is very hard and resistant to abuse. It looks better if waxed but can be left for the life of the boat without waxing. Have seen quite a few boats that look like that's been their history. A lot of people think you have to compound the gelcoat before waxing. That's a great way to shorten the life of gelcoat by grinding it away. I found 3M Finesse brought back the shine with a wax job after. PO's had buffed the hull so many times the gelcoat was nearly worn away down to the underlying laminate. Didn't have a choice but to paint it.

Avoid painting an FRP boat as long as possible. Gelcoat shrugs off abuse that will scuff, scratch or otherwise damage a painted surface, even LPU paint. The paint looks great but will not last as long as the original gelcoat by half or more.

Re: Fiberglass maintenance?

Galaxy girl, you've seen all the other contributions on the subject. All I can say is that my boat is 40 years old, solidly built like a proverbial brick outhouse in fibreglass. It gets thoroughly washed once every 4 months or so, lifted out every 4 years and a full 'bottom job done, anodes, anti foul etc.'. Yes,after years in the UV light of the Mediterranean the surface of the gel coat will go dull, you have a choice, wash and polish it every 4 months, or 800 wet & dry paper then wax polish every year, your call. In my opinion NEVER paint it, I had one hull done on a previous boat at great expense years ago and it was the dogs bollocks for about 6 months ! after that I could never keep it looking good.
I wouldn't have the gift of a steel boat, I've seen too many stripped to the stringers but each to their own, the newer versions with epoxy paint and extruded polyurethane insulation would be worth a look, if it weren't for the external painting. Life's about cruising, not painting.

Re: Fiberglass maintenance?

Thanks everyone for all of the helpful information. I'll admit that it's all a bit confusing, but I'm not going to get too hung up on the details now (I'll save that for later) The general feeling from everyone seems to be low maintenance as compared with steel and wood. If I end up with this glass boat I can figure out the wash, wax, paint schedule in more detail.

Re: Fiberglass maintenance?

Just a thought and a question. Is GG real? Or is someone pulling our leg. It's just hard for me to completely believe the total lack of knowledge and the questions being asked from some one with five kids looking for a 60 something boat. It sounds more like a great put on.

Wow, I'm surprised people like you are still asking if I'm real. I have a blog with my kids and my pic up for goodness sake. Or is that an elaborate hoax too? Do you really think I'm going to put all this effort into something that isn't real.

I think it's just hard for some people to believe that the world doesn't revolve they way they think it should. Some people, like me, are VERY out- of -the- box, and I think that's it hard for someone like you to understand that.

What's the big friggin deal anyway? I'm selling my house and buying a big boat. So what? Why is that so unbelievable? Lots of people do the same thing all the time. And, so what if I have zero experience, that's already been done too. I'll learn! Believe me, I'm not the first and most definitely will not be the last.

i bought a 45' sailboat, and still have no clue how to sail it
it must be something you can learn. the first sailor must have been clueless too, but he survived to tell someone about it....

Re: Fiberglass maintenance?

All of us should be positive in providing answers related to what we all enjoy; sailing/flying. Sailors, like pilots, like to help each other no matter what the question or background might be. Berating/ridiculing someone will serve no purpose. If I have a question, no matter how trivial it may sound to you, I hope that some of you will share their experience/knowledge with me as well as with the rest of us.
