Since the gel coat on the 66 sport I just bought is apparently beyond buffing out (hairline cracks in a crazed pattern) and everyone seems to recommend AwlGrip paint I have decided to go that route. Where is the best place to buy the stuff? I will need both the tan and the blue as well as primer/surfacer to fill the "crazes".

Also, How much will I need cover the boat a couple of coats inside and out?

Bruce check out Interlux Plus two part and their priemer -- might be easier to use than Awlgrip ---

Bruce -

You _should_ be able to pickup Awlgrip at a local West store. Are you going to spray or bruch it on?

If you are experienced in spraying, I'd also check out the Concept 2000 line from PPG(?) available at a good auto paint store. There they can custom mix as much as you need, after they analyze your hull color with an instrument. I ended up having my windshield frame, transom (new engine) and forward platform painted with this, and it is really hard. If you used any 'thane product and finish it off with one or two coats of the recommended clear coat, it would really shine!

If you don't spray, and still want the sprayed look, one way would be to contact a good repair shop, work out a deal where you do all the grunt work of prepping, repairing the cracks (one thing to note about paint vs a re-gel is that with paint being thinner, you've _GOT_ to repair more little cracks then you would have to with the re-gell), sanding, then have the paint guys shoot her.

Along that line a thought... if your aquainted with a local new car dealer and they have a well run, clean facility thats using the newer downdraft paint booths, etc., they may be the shop to contact first, over the small shop. Check to see what type of products they use.

Hey Don the reason I suggested Interlux is you don't have to be to finicky about those cosmetic spider cracks. You just sand them out of the gelcoat which you have to do anyway and then use Multithane primer this can be built up with multi coats filling/eliminating many of the small imperfections which are a pain -- believe you can build up to 20 mils with it --- with little sanding -- (a technique used pretty routinely now is to sand blast the hull with either super fine sand or media -- fill any cracks or gouges sand them smooth -- lightly smooth out the entire hull and then use the primer in multi-coats and at least two finish coats of Plus --- you can rent a sand blaster and/or compressor for a day at most rental places and a two around here even carry sand and grades of media which can be used a couple of times if you vacuum it up -- the sand can't)

Plus is the only one that will self level I know of in a two part so spraying isn't necessary.

I have seen a couple of large sailboats finished with Plus rolled on and I must say it turned out to be a wow finish --- which has lead me to decide to use it on two Sunfish hulls we are donating to our daughters Girl Scout Camp since I won't have to fool with spraying --- I do know how to spray have both standard and HVLP rigs but this 2 part poly stuffs to thick unless you use way to much thinner for HVLP which translates into many more coats than necessary --- conventional spraying makes a real mess unless you have the proper spray booth and evacuating equipment -- over here in NJ a decent shop will still charge $50 to $60 an hour just to spray and as you well know it just isn't spraying even if the hull is prepped good still sanding between coats so for a 13 inside and out a rough guess around these parts would part you with between $350-500 labor only --- which is about the cost you can add to that for the paint and materials ( might add it ain't just "shooting it" whether Awlgrip of Concept 2000 multi- coats of primer have to be sprayed /feathered and at least 2 coats of finish --- on the outside of the hull suggest 3--- and no shop I ever ran across wants there customer running in and doing the sanding etc. after they start a job --- liability and it screws up the shop routine).

Bruce as Don mentioned West carries all the necessary materials for all three finishes --- if you go with the PPG stuff might save a little though at local auto parts supply --- you also might try any other local marine supply and save money over West --- none of three systems is inexpensive --- gelcoating is actually material wise less expensive but the labor factor and pro application factor way out strips the 2 part poly systems in overall cost!

Just my thoughts for what there worth each has their own and it obvious I have mine --- chuckle --- all ideas/thoughts are always welcome around my camp fire ---- we may disagree but hey that's life --- Tom

WoW! Now I know it all! I have spray equipment and a spray booth so that is not a problem. I spent some time last night reading up on the awlgrip system on their website. I am not familiar witht he Interlux system but will take a look at it. Just how tough is spraying the gelcoat anyway? Can I get a reasonably good job or should I stick to paint? I have been spraying for about 25 years. I don't know if this experience applies since gel coat is alot different then paint and clear lacquers.
I'll keep you posted. It probably won't happen very quick.

Just read Eric's post above. Maybe I won't attempt the gelcoat.

Bruce: if you want gelcoat, don't be put off my my experience with the boatyard. I gelled a 30 year old 13 myself a couple of years ago, and it gave me no trouble at all. The difference was that I was working over the original gelcoat. In the case of my Nauset, the boat had been painted, and apparently the yard got lazy and didn't remove the paint. When I gelled the 13, I just sanded it, wiped it down with acetone and rolled on the gelcoat. It didn't look too great for the cosmetics, since I never sanded it, but there were no problems with durability or blistering. Since I didn't own the boat (it was a perk for a job), and the owner had no interest in it, I just wanted to preserve it without doing too much work.

I should specify: I didn't wet-sand and polish after finishing the job. I did sand in preparing the surface prior to applying the gel.

Thanks for the info. I'll have to look in to this one deeper.

I just refinished a 17 footer that was a fish and wild life boat 1971 model. Boy was it rough!~ many spider cracks etc. I had it blasted with baking soda (Commercial Arm and Hammer) It's a mild medium where you can paint the surface without sanding before the first coat. Follow with interlux 404/414 barrier coat as a primer. Use two coats. Sand with 220 between coats. Follow that with Interlux interthane plus (Two Part Epoxy) Its a roll-on brush-on that is fantastic. I used four coats. Wet sand between coats with 320. U Call Interlux hot line 800 number if any questions (very important and technical assistants very helpful. Their web site is
