I'm trying to do some minor repairs to my fathers Robalo 1820 boat(http://robaloboatown...?showtopic=2296). There are a few areas on the deck hatch that have missing/chipped fiberglass. Any advice or suggestions would be appreciated. Also if anyone knows about replacing seating bracket/pedestals, that would also be helpful. They are pretty basic, although we do have seat cushions for them, but the swiveling pedestal itself has so much play it in. What size do I have? Can i get a universal replacement?

The pedestal would fit the chair As the bolt pAttern usually the same . We would just take the standard pedestL and base and cut the pedestL to fit. As far as the livewell it was built in house in the mid to late 90's

Thanks for replying. When you say "we", do you mean you work for Robalo? Or a boat repair shop? I would have to get the pedestal I'm interested in, modified to fit my seat?

I was also searching the internet for boat fiberglass repair, and to my understanding the outer white finished part is called the Gelcoat? Could a DIYer do a satisfactory repair job with the right tools?

WE yes but in the early years '69-93" I was there and/or working there . The pedestal seats had a plastic part on them and will look at PoPs today if I can take a pic of one for you. As far as fiberglass repairs do some searches 2-IN-TOW is our resedent glass man as well as some of us others . But you can get as much as you need and can read but untill you start it is hard to understand but not as hard as it sounds. WE will have your back. good luck. :captain:

You can do the gel coat repairs yourself. Just depends how big the area is you plan on repairing. Take some detailed pics of the area and we can point you in the right direction. The easy part with gel coat is you can build it up and then sand it smooth. You need to get rid of all the cracks first though.

Here are some more areas needed to be fixed. As you can see on the keel, it has sustained a bit of damage to the fiberglass area as well. Would anyone recommend repairing with fiberglass cloth as the youtube video provided describes? I really need to know what materials i need to buy, what type& brand gelcoat. Was thinking of installing Keel Guard in the future, too. Any suggestions apprecites as always.

No need to glass that keel. It appears that only the gelcoat is missing. Fix is simple. Blow out any loose debris and wash the open area with acetine to remove any oil / grease / contaminants. Tape around the area to be patched. Get a quart of white gelcoat with wax additive. Mix gelcoat and hardner according to instructions, then mix in cabosil to make a paste. Be sure to mix hardner first, then cabosil. Once mixed, use a spreader to force the paste into the damaged area. Overfill the patch as the gelcoat will shrink slightly as it cures. Try to get the patch done the first time (makes it easier!). Let it set up until thoroughly cured, depending on the temperatur. If air temp is 70 degrees, it should be kicked and ready to sand in a couple hours.

Rough sand with 80 grit to see if additional gelcoat is needed. If not, break out an electric dual action sander and rough sand with 120 grit. Follow up with 220 grit on the sander, then 320 wet/dry. At that point, I would say good enough.

Do these brand look good enough to get the job done. I think i might need a gallon since i have several different areas needing patched. Would a QT of cabosil be enough?

Check the prices at http://easternburlap.com/ . One gallon of white gelcoat is 40.85. Be sure to tell them you want the wax additive added to it. I don't think there is a charge for adding it.

Also, I think you will be suprised how much coverage one quart of gelcoat will give you, even when thickened with the cabosil. I would recommend going with one quart unless you have a LOT of area to cover.
