No it cannot be used over epoxy. I messed up and used 2-part epoxy fillersto fill small voids and smoothing out the bottom and polyester gelcoat willnot sure over these areas. I have tried all the tips and tricks and wasnot successful. I will probably try epoxy resin gelcoat with tint to coatmy boat.

I have used it to fill in deep scratches on two golf carts I have at work. I hope this helps.

These gelcoats can be used on top of epoxy as well as polyester resins for cosmetic repairs, but it must be properly and thoroughly cured. We have found that for larger scale work than small cosmetic repairs, using an epoxy barrier coat or tie coat before gel coating improves the adhesion.

Yes you could, no need to seal out moisture as it air drys. Ad heat from heat gun to speed up process. Good solid product!

In short, this product can work for you, but you may prefer non-waxed gelcoat, depending upon your repair approach. If you plan to address each crack individually, each crack can be ground out and cleaned. The air-dry gelcoat can be applied to the crack using a wooden mixing (Popsicle) stick. A stick is easier and cheaper to use than a syringe. If the gelcoat color doesn't match your existing gelcoat, the repairs may be more visible than you would like. If you plan to grind out and clean all the cracks, and then apply a new gelcoat layer over the surface, this product can be used, but you may prefer a non-waxed gelcoat. Regardless of whether you use this product or a non-waxed gelcoat for this approach, I would recommend filling the cracks before you apply the new gelcoat layer over the entire surface, otherwise you will likely have low places where the cracks were ground out. I used this product to refurbish the non-skid in our sailboat's cockpit, an area about 2 feet by 4 feet. My larger plan was to use it for the entire non-skid area on our decks, and this was a limited area where I could try the approach. After removing the steering pedestal, scrubbing with Interlux 202 solvent, grinding/cleaning/filling a few dings, and abrading the surface as best I could, I cleaned the surface with acetone and then applied this gelcoat. I tried a small roller and I tried brushing it on, but had the best result stippling the gelcoat with a brush; that helped get it into the texture of the nonskid. Unfortunately, I needed a second coat and, after that found that I hadn't covered one area heavily enough, so had to add more there. With this air-dry product, I had to again dewax (with 202 solvent) and abrade the surface before each additional coat of gelcoat. I have since completed our cabin top using a non-waxed gelcoat and I much preferred the non-waxed version because I could add additional coats as needed without waiting for the previous coat to cure, and then dewaxing/abrading. I still have to do the side decks and will be using non-waxed gelcoat for that.

You can V out the spider cracks and crazing with a dremmel or similar tool, and fill them with gelcoat, but depending on the root cause of the cracks, it may only be a temporary cosmetic repair.

Hi! We are able to get most colored gelcoats without wax as well. Oyster White without wax is regularly in stock here.

Look at the Awlgrip color chart, they match those colors.

The colored gelcoats match the Awlgrip color pallet. Still, I'd order the necessary tints to go along with your order to get the best match. Oyster white was the closest match for my Dolphin 24, but I got yellow, brown and white tints to fine tune the match for my application.

The colors are close to the standard Awlgrip colors. You could call to have a color card mailed to you.

If the gel coat is set then you must wait for it to cure, sand and clean before next application. It usually sets fairly quickly so it's not like you have to wait a long time.

Thanks Rosalind much appreciated this helps a lot and answers my question.Have a Great Day.Ray

This is gelcoat which is used to fill and repair scratches in existing color. If you are repainting then I don't know if this is the best way to go. I'm just a boat owner and have never repainted a boat so I don't know the right answer.

Josh,Gelcoat may not be the best product for your project. I'd suggest looking at 1 part or 2 part epoxy paints. Mask between colors with a good quality tape for the two tone paint scheme you desire.

The colored gel coats at Jamestown match the Awlgrip color chart. I got one from Jamestown several years ago. Still, I'd plan on getting tints ( the small tubes of colorant: yellow, brown, white, red or blue) adjacent to the color you're trying to match for fine tuning. Adjust the tint on a small amount of uncatalized gelcoat, put a dab near the area you're trying to match and wipe it off and readjust if you're not happy with the color. Keep track of how many drops of tint you add so you can replicate in in a larger batch if necessary.

thanks Mike I will ask Jamestown for a color chart totim

If the scratches aren't too deep, you can sand the entire area to blend fair, clean and dewax, then use a preval sprayer to touch up the entire area. You may need several coats to cover and with air dry gel coat, you'll need to lightly sand between coats. You'll want to order styrene as a thinner for spraying, acetone as a cleaner and white, yellow and brown gel coat coloring agents to fine tune the color match to your boat. ( due to fading, older boats are no longer an exact match to the original factory colors. Adjust the colors to un-catalyzed gel coat, put a dab on your boat and check for color match. If not right, wipe off with acetone, adjust the color and try again. 1 or 2 drops of coloring agents make a big difference. Good luck!

If they're deep grooves it'll fill them like putty if you apply it correctly (which is not easy) but will hardly be noticeable if you get the color match correct. If they're shallow try sanding them out and buffing (step 4 only). 1. sand the scratches (inside the grooves only) with 320 grit so the GC will adhere.2. mix/apply GC like putty filling all sanded grooves.3. allow GC to cure4. block wet-sand smooth and polish taking care not to sand through the existing GC (320 grit --> 500 grit --> 1000 grit --> 1500 grit --> compound / buff)

I only had a small repair to do about 4 square inches so it is hard to answer your question. This stuff is extremely thin, like water and it cures really fast. I had to use a lot of coats to build up any thickness. The color was a perfect match though.
