Yes, you can apply gel coat to wood surfaces. Gel coat is often used on fiberglass surfaces, but can also be used on wood to provide a durable and glossy finish. Make sure to properly prepare the wood surface by sanding and cleaning it before applying the gel coat for best results.
All fiberglass has a final coating of gel coat, it could be marine gel coat, tooling gel coat, or swimming pool gel coat. Typically, swimming pool gel coat will last about 20 years before it loses effectivness. At that point, algae becomes able to "cling", the surface begins to stain, and the actual fiberglass becomes evident to swimmers, causing scratches. There is only one solution, lightly sand off the remaining gel coat, wash down the pool, apply one coat of vinyl ester resin, and roll-on 3 coats of swimming pool gel coat. The pool will be as good as new for another 20 years, provided the pool is properly cared for.
Vinyl liner pool steps are constructed of fiberglass, vinyl ester resin, and swimming pool gel coat. Staining (and blisters) occur around the pools 20th anniversary. It's caused by a breakdown of the white finish called swimming pool gel coat. Stains and blisters can only be removed by replacing the now porous gel coat with new nonporous swimming pool gel coat. Done properly, the new gel coat will last another 20 years.
No, it isn't necessary.
Most of the old gel coat must be removed. Although swimming pool gel coat does begin to break down within 20 years, sufficient non-porosity remains to preclude long term lamination.
For most fiberglass swimming pools, it means that the pool is at least eighteen years old and is in need of new gel coat. All things fiberglass have a finish coat of gel coat. Because swimming pools must contend with harsh chemicals, the swimming pool gel coat does not last forever. The longevity of the gel coat depends upon two factors: 1) the pool manufacturer, and 2) proper maintenance. There is a huge difference between manufacturers. Gel coat replacement ranges from 27 years at the top, to as low as 4 years, or less, at the bottom of the list. But the average for most fiberglass swimming pools is around 20 years. Nevertheless, chalking always means that the nonporous gel coat has become porous and needs to be replaced with new swimming pool gel coat as soon as possible.

Well, I logged onto this site to answer questions about the mercury capri..specifically the 90-94, but since I'm here and a resident expert in the marine (boats) filed of operation as well as auto tech...lets go through this one as well. First: You have a bayliner capri...so sorry. seriouslly, bayliner has a major issue with this issue. Now, a little info. You have no noticible leak. All boats that are fiberglass have what is called gel coat over the fiberglass laminate below...this gel coat looks like paint but it's actaully a polymere. Gel coat is actiually porous in nature but does not look like it, and it was never meant to be a water barrier. Water actually trasverses through the gel coat of your fiberglasss boat while in the water and when it does, it gets water inside the fibeglass substrate below the gel coat. The water actually can pool up within the hull and depending on fresh water (MI) or slat water(FL) it can destroy your boat over time. A blisterd boat is the prime example of why gel coat was a major no, no to use by all the manufatures witn the marine industry...and all of them did use it. Some are actually painting there hulls now with awlgrip...a urethane paint to seal out the water. You will continue to get water in the bildge of the boat no matter what you try and do...this is the unfortunate nature of gel coat/ fiberglass procedure. make sure you have a good bildge pump and try and keep it as dry as you can. Short of painting the entire bottom from the waterline down you have no remedy. A word of caution...you must make sure the hull is completely dry prior to painting the bottom or the paint will eventually blister and well you don't want that know do you. Sorry!
Yes, Bunnings typically carries a range of gel coat products for fiberglass repair and maintenance. You can check with your local Bunnings store or their website to see their current selection and availability.

Blisters are caused by a breakdown of the swimming pool gel coat, which occurs after about 15 to 20 years of use. The problem is easily and inexpensively solved by removing the existing gel coat, and replacing it with exactly the same product that was used originally. Every 15-20 years thereafter, you'll need to remove and reapply the swimming pool gel coat. It is imperative that this be done once every 20 years. At the first sign of blisters, stains that can't be wiped away with detergent and a cloth, or algae that is able to cling to the surface, you'll know that it's time for new swimming pool gel coat. These are all indications that the non-porous gel coat has become porous and must be replaced.
