gelcoat does bond to a properly cured and prepared epoxy surface.
There is a common misconception, fueled by some gelcoat manufacturers and by some expensive failures in the field, that gelcoat will not bond to epoxy. Polyester resin bonds poorly in a secondary (mechanical) bonding situation which consequently makes epoxy the resin of choice for repairs. How can one be squared with the other?
The answer is surprisingly simple - gelcoat does bond to a properly cured and prepared epoxy surface. There are a couple issues to be aware of to have success making this repair. There are three situations that cause gelcoat to not cure over epoxy... all related to the hardener chemistry. Epoxy hardeners are basically a blend of amines, which can terminate the chain reaction of the radical molecule that is the basis of polyester (and vinylester) cure chemistry. So by carefully mixing, curing, and preparing of the epoxy so that there are no unreacted amines to interfere with the gelcoat cure, gelcoat bonds quite well to epoxy.
The first situation is undercured epoxy. Gelcoat applied to undercured epoxy will be in contact with unreacted amines and the cure will be halted.
The second situation is if the epoxy is mixed off ratio so that it is hardener rich, again leaving unreacted amines free to interfere.
Third is the issue of amine blush, commonly called blush. Blush is a surface phenomena that is a reaction of the amine molecules at the surface with the carbon dioxide in the air. It forms easiest in the presence of moisture, so working in cool, humid environments will maximize the formation of blush. Any amine hardener has the potential to blush, Regardless of chemistry, blush is very easily dealt with because it is water soluble. A simple wash with clear water removes the blush. No soap, no solvents. Then sand that washed surface with 80 grit paper to provide the gelcoat with sufficient key so it won't run. Be sure to use non-air inhibited gelcoat that has a paraffin wax added. Gelcoat is applied over epoxy on a routine basis everyday in boatyards that are aware of these issues.

1st Time User
After being ripped off, I decided to personally repair the damage to my decks left by so-called professionals. Mike's videos walked me through the process. I also called and e-mailed him. Each time he provided the information I needed to complete the job. FiberglassSite.com has a great product. My decks are now looking good. I am confident that I can handle any future issues that my come up.

Great Stuff
I had to reinsulate the fridge on my boat. After that was finished, there were 42 holes that needed to be fiberglassed over. Everyone knows you can't have plain fiberglass mat poking out everywhere in your fridge, so we covered it all up with fiberglasssite.com Gel Coat. This is heavy duty stuff. I don't for see my beer cans scratching or denting this stuff! The how to video's are a major plus as well.

Gel Coat and a 30 year old RV.
I have been offered an opportunity to revue www.FiberglassSite.com White Gel Coat. It is simply amazing. Let me state that I am/was a first time user with no experience with this product or anything like it. In fact I don't remember the last time I used a paint gun. That being said, these were my experiences with this product. First I would like to praise the company. They were polite, fast and efficient in the ordering and shipping processes and I received the product in good condition much faster than I expected. Then there is Mike Levaro. Knowing so little about what I was doing, he was a fountain of information. I would fire off half a dozen questions by e-mail and within the hour he would have the answers in my inbox. With his help and the online videos he supplied I had the confidence to tackle the job. The job was a 30-year-old fiberglass RV that was in very poor condition. I had recently bought it for a fishing vehicle but it was so ugly my wife wouldn't ride in it. The fiberglass was deteriorated until it looked like hair. The decals had cracked and split and each fissure caused more degradation. It was awful. I spent the first two weeks with a hot air gun, assorted blades and scrapers, some wire brushes and Scotch Brite wheels, removing those decals. I am in my seventies so it was a long and tedious job. I tried, with varying results, Goo Gone, Goof Off, Aircraft Decal Remover, Bug and Tar Remover, Acetone and WD-40. In the end nothing worked better than heat and elbow grease. With the decals finally gone I turned my attention to sanding. It was a mess. The fiberglass was so deteriorated that the more I sanded the hairier it got. Then I thought back on something Mike Levaro had said. "If sanding is required put in the hardener and wax, then sand it." I applied a few light coats of Gel Coat with hardener and then one light coat with hardener and wax. This "fixed" all the hair and fuzz to where it was stiff and brittle on a rather smooth and slick surface. Sanding then became a breeze. One more heavy coat with hardener and wax and I was ready to re-trim. A beautiful finish and a 30-year-old RV that looks like it just drove out of the factory. Lessons learned. Trust Mike Levaro, he knows his business. You have about 20 minutes to use the mixed product. Then if you are smart you will stop, dump anything left in the gun and clean it thoroughly with acetone. Then mix a whole new batch. If you just refill the gun and go on spraying, it will start to set up and give you trouble. I found that with my gun and air compressor, adding 6 oz. of acetone to the quart of product gave me the best spraying results. www.FiberglassSite.com makes an excellent product and is a good company to do business with. I am looking forward to my next project. Bill V. Tucson AZ.
