TotalBoat Polyester Fairing Compound drags smoothly, sets up fast, and sands like a dream for quick and easy cosmetic repairs on boat gelcoat, fiberglass, and other composite surfaces above the waterline. Premium thickened polyester resin fills, fairs, and feathers to perfection, so repairs blend easily into surrounding surfaces.
This high-viscosity polyester marine filler is easy to mix with the included MEKP catalyst to achieve a smooth, creamy paste that spreads easily, feathers well, and sets up quickly, without sagging. In as little as 30 minutes, it cures to a hard material with optimal strength and easy sanding ability. It's easy to maintain a feathered edge while sanding thick or thin areas, so with very little effort (and very few sandpaper change-outs) you get a perfectly smooth, pinhole-free surface that's ready for paint or gelcoat.
This lightweight cosmetic filler also has minimal shrinkage and less odor than traditional polyester fairing compounds. In addition, you can tint Polyester Fairing Compound with polyester resin-safe colorants for a closer match with existing gelcoat.
Polyester Fairing Compound has many uses including composite tooling and repair applications, but is designed for use as a fairing material only. For high-strength repairs to fix deep gouges, cracks, dings, dents, and small holes, use TotalBoat Polyester Structural Repair Putty first, allow to cure, then apply TotalBoat Polyester Fairing Compound. If used below the waterline, Polyester Fairing Compound must be overcoated with an epoxy barrier coat primer.
Compare to 3M Marine Premium Filler, FGCI Gelcoat Putty, Evercoat Polyester Glazing Putty, 3M Platinum Filler, 3M Platinum Plus Filler and 3M Platinum Select Filler. All TotalBoat products provide great value and great results. 100% made in the USA.

So simple to mix and apply. Equally easy to sand and shape. Couldn’t imagine using anything else.

I've used most of a gallon of this fairing compound on a boat rebuild, and it's been very useful for filling all the imperfections in the fiberglass. However, it is so thin that it falls off the applicator tabs (I'm using plastic applicators like you get with Bondo) and I've wasted quite a bit due to this. Probably 1/6 has ended up where I didn't want it. It hardens up really well and sands to a feather edge, so not much else to say negatively. everything else is my own skill issue.

Jamestowns epoxy fairing is excellent, this stuff is the worst fairing compound I’ve ever used. The cans were full of lumps. As its polyester with a MEKP catalyst it needs to be starved of air to cure out completely even though they say it doesn’t require wax or peel ply, it does. Without starving it of air it just gummed up my extremely expensive festool sanding discs and REALLY pissed me off. DONT BUY THIS STUFF!!

This product is easy to mix and very easy to work with. Sanding afterwords doesn’t take much effort at all. Great product.

This stuff is about the consistency of mayonnaise and mixes and spreads easily. It is basically like auto body spot putty, only for FG work. One warning - it cures rock hard so don't apply any more than necessary with the thought that it can easily be sanded off later... Wrong! It will take some major elbow grease...

When spread thin it does not cure, just like all other comments are saying, not happy to have to remove all this uncured product from my hull.

I am an over 50 lady, and I (by myself), sanded the cabin tops of a older 45 ft sailboat down to the original clear coat (6 layers down). I prepped using Total Boat’s fairing compound, then sanded and applied 2-coats of primer (sanding in between coats with 250 grit). I applied very thin coats of this paint (mixed with the Total Boat thinner), let them dry overnight, and sanded in between using 250 grit. I applied a total of four coats (before the last coat I used 350 grit). This was not difficult to do, and I found that the paint applies very nicely. I applied it in S. FL, in the early spring (temps were in the 70s to high 80s). I did not brush tip it, just rolled it using high quality foam rollers. It was dry to the touch within 2 hours, and I always waited until the next day to sand. I also washed the cabin tops with soap and water after each sanding, and then wiped the surfaces down with a cotton rag dampened with the thinner before applying the next coat. The results are amazing! I found there was no need to brush tip as the paint spreads well and lays flat. But, I am a perfectionist, and also only mixed small quantities of paint at a time (
