Polyester Fairing Compound - Quart Kit | Polyester Filler Putty for Fairing and Repairs on Fiberglass, Gelcoat and Wood; Sands Easily for Marine Primer or Paint

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...

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 (<500 ml) and made sure to add additional thinner as needed. I will be doing the decks of this old boat next, and using Total Boat!

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.

I laid down my track bike and needed to repair the fiberglass fairings. This worked great as a filler. It’s stuck well seems to be pretty durable and was not that difficult to sand.

I have used this product for making smooth repairs on my boat prior to a gel coat spray job. Works great.

I ordered a quart can of this TotalBoat - 512949 Polyester Fairing Compound, the can arrived , upon opening it, it looked like 20% of the content's was missing. I contacted the manufacturer and was told that was normal & the space was left open to mix the 1/4 OZ of MEKP ????. I contacted Amazon explained what happened & they sent another quart can. After reading bad reviews on the compound not curing properly I mixed 1/2 oz by volume with 8 drops of MEKP,,,it never cured and would not sand at all without gumming up the 80 grit paper immediately . When the second can arrived I did the same 1/2oz - 8 drops MEKP & did not cure after 2 hours , same with the sanding.. NG, you might want to pass on this product. lots of other experiencing the same.

Exactly what I needed for my project! Good quality! Thank you!!!

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

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.
