I need a couple of answers I started sanding the exterior and want to know the precedure. I need to sand and rough everything. Then fill in spots that have bubbles with putty do I need to gel-coat all exposed or puttied spots and then prime and paint.
I have heard from the boat store that with the new paint systems I don't need to gel-coat over the spots with bubbles after I have repaired them. I guess that is my question I am a little confused about what to do I need a little help.

I am using a resin and fiberglass based putty I add a catalyst to. I have purchased for mini-craft in florida. Mini-craft calls it their reinforced "A" putty.

If you are going to prime and paint with a 2-part marine paint like Awlgrip, then you do not need to gelcoat at all. Decide on the paint first and then follow the manufacturers instructions for filling and sanding.

I talked to the Area rep. for awlgrip? I was told that if I was to use the system that they have 1st. it is very expensive and 2nd. if I was ever to leave the boat in the water for any lenght of time that all the paint could peel or blister is this true.
I then called a local repair and paint dealer and proceeded to ask a bunch of question and was told the only way to do a proper job was to regel-coat is this true are these my only 2 options? Do I have any other way of repainting the sides and bottom of my boat???

You might also want to check into the Interlux products that are avaiable, which should be less in price than Awlgrip.

Two part poly pant such as Interlux, Sterling or Awlgrip will blister if they are used below the water line and the boat is left in water for any length of time. On a trailer boat this is usually not a problem. A few days or a week in the water is not likely to cause blisters. All of these paints are sold for use above the water line. All of these suppliers recommend their own brand of bottom paint to be used as part of their system. That is, two part above the water line and bottom paint below the water line.

I am going to paint my 1976 -13 sport with two part above and below the water line. It will be rare that I will keep it in the water for more than 48 hours. I will be able to report back in a year or so if it was a good or bad idea.

Joem, another choice widley used on damaged glass through the gel coat is West Systems epoxy. It's a 2 part system that is good for repairs to the blue color or through the glass. When dry it can be sanded and then wet sanded before painting for a nice finish. Awlgrip is great for above the water line or trailered boat. But if docked for extended time Interlux bottom paint is best. Hope this helps.Regards, Jay

If you go to Cetacea, page 41 and scroll to the bottom pictures you will see Rex Bettis's Montauk. I have seen this boat in person and I can tell you it's the best looking Montauk I have ever seen, bar none.

This boat was awlgriped inside and out. I can tell you that this boat even looks better in person. You can't see the detail and quality of workmanship, but real craftsman worked on this boat.
