rejuvenating old gel coat vs. re gelcoating
I'm in Florida so I can do things all year long. A couple of months
ago--just after the Miami boat show--I applied poly glo to my mildly oxidized topsides. It came out OK--not like a newly buffed and waxed gelcoat in good condition--but OK. Now, a couple of days ago I taped off an area around my forward hatch and regelcoated the entire area, using a spray gun and a special gelcoat additive (I think it is called Duratec or something like that). It came out fairly smooth, hardly any orange peel. A little sanding and buffing and it looks perfect. This causes me to wonder: Why could one not simply sand and fair the complete hull and shoot on a new gelcoat? I think I would rather have this than awlgrip since gelcoat is so easy to repair. Anyone had any experience along these lines J. |

Most of us don't have the skill or tools to do it, but it seems you do. Friends do that for a living. -- Jere Lull Xan-a-Deux ('73 Tanzer 28 #4 out of Tolchester, MD) Xan's Pages: http://members.dca.net/jerelull/X-Main.html Our BVI FAQs (290+ pics) http://homepage.mac.com/jerelull/BVI/ |

Anyone had any experience along these lines Before you sand off the first two layers of mat, try a square using Meguiar's Fiberglass Restorer. It's real easy. It does the same thing to gelcoat that Meguiar's paint restorer does to an old car finish all oxidized. Use Meguiar's wax to keep it that way.....no sanding needed, an afternoon job. Works even better if you drink a fine English ale, while waiting for the restorer to dry!....(c; Shh.....don't tell the boat stores Autozone has it for 40% less money....ok? |

For gelcoat restoration ... or for removing blemishes when a boat is
pulled from its mold: Flat sand with 2000 grit wet and dry . Begin with coarser (1000, 1300, etc. if removing heavy oxidation. use a rubber block. . Get a high speed (variable) autobody shop polisher with LAMBSWOOL bonnets. get 1000, 1300 and 2000 grit compound (3M sells even finer grades) On a 2 ft by 2ft area begin with the coarse grit and buff, change bonnets and use sucessively finer grades, then wax with a natural carnauba wax to fill the pores of the gel. Never mix grits and bonnets. Dont push the polisher into the gel; keep it moving so it doesnt burn the gel and be careful over sharp edges. This method will usually restore gelcoat to showroom NEW condition. Usually the gelcoat is thick enough for MANY / SEVERAL such buffings... but stop if you start to see the color of the matting layer start to show through ... then its time to respray new gel or get out the paint can.. If you dont want your gelcoat to look like **** after a few years, every few years strip out all the old dead wax with a strong caustic detergent, then lightly buff and rewax to keep the pores sealed.
