Just got back from the fiberglass shop and they told me not to do any gelcoat work. So I am wanting to redo the exterior gelcoat. Are there any good books, literature, or threads out there from prepping the existing surface to spraying gelcoat to finished product? All I have been reading about is how to patch or repair gelcoats. Haven't seen any info. on redoing entire gelcoat. Boat is a '71 Katama, also has little tiny cracks on the deck surfaces where sun has gotten to gelcoat. I am wanting to try the gelcoat myself, I don't know where to start. The fiberglass shop also hinted around that it could take 10-15k to redo the whole boat. He said he wouldn't put that much money in to the boat. The hull has started to turn yellow and color restorer compound won't do what I'm looking for. Boat is gutted and stripped down to the bare hull ready to get started. I have been taking pictures since I started and would like to share my experience with others after boat is completed.
Thanks for the comments.

Find another shop. I've had quotes that range from a low of $2500 to a high of $6000 for my Montauk.

I did mine myself w/out any prior knowlege of spraying gelcoat. It's not a bad project, but there is WORK involved....but to me, the results were well worth the work.
Most of the books I found were for new gel-coat in a mold....with an old boat, you don't have a mold.....
I put my page together (from an amateur's perspective) to try to help others. I'm no expert, but what I've prepared is what I did and worked.
Hope this helps!

I found a real good series of 3 videotapes that go into detail on fiberglass work. I bought them via Ebay. The publisher is Bennett Marine Video, 730 Washington Street, Marina Del Rey CA 90292 213-821-3329. Volume I = Basic Gelcoat damage repair and Finishing, Volume II - Stress Cracks, air voids, and fractures, Volume III - Color Matching & Finishing. They tapes have been a great help to me.
There's a great thread on this in the reference section of this site as well with some excellent pictures.

I just finished a gel coating a 18 foot 6 inch Raider hull (outrage) inside and out. I had very, very limited experience with either gel coat or sprayers. My costs were approximately 8 gallons of gel coat- $ 250.00, 3 gallons of vinyl ester primer $ 240, 2 cheap hvlp spray guns for less that $ 100. and a Makita compressor used for $100.00.
Its quite a bit of work, expect to make a lot of mistakes at first, but I found it very rewarding. I’m told the finished product look pretty good and I am well satisfied with the job me and my girlfriend did. The next one I have every confidence will look excellent.
Start with the base. Get the faring and primer as perfect as possible before you start the actual gel coat. Check your temperatures (it’s best to spray above 70 – 80 degrees) Read the posts here. These folks have a lot of collected knowledge that will be very useful. And then just go for it. Try to flip the boat over so the hull is up. It makes working a loot easier. I made the mistake of gel coating the outside of the hull from under neath. BIG MISTAKE! And it’s really not brain surgery. If you are the least bit handy you should be fine.. Any specific information you need please feel free to contact me,
