Best non polyester fairing compound

[unbusted67]

I am going to be faring out some rough unfinished fiberglass surfaces on the interior of my boat and I am doing it under shrink wrap so I don't want to deal with the stench of polyester. Is there a good epoxy faring compound that comes in a can?

Awlgrip, Alexseal and International all make good ones. Or regular epoxy with microspheres works good as well.

Awesome thanks. Do you have a preference? I like Interlux products just out of familiarity.

System Three "Quickfair" . It's a two part epoxy faring compound that is formulated under vacuum. It applies like butter and sands very easily without build up on sanding pads. Although it seems crazy expensive, it performs so well and saves so much time and effort, it's actually worth it and I'm an overly thrifty person.

I like Interlux Watertite.

Watertite is great but it is for final filling, it is more like epoxy bondo.
International makes a putty that is grey for heavy filling, then a green for medium filling, and Watertite of final fairing.

If you have a large area that needs alot of filling, the gray is the bomb.

+1 on Quickfair.

If you are under shrink wrap in Maine, be aware that any epoxy product can have a very long cure time in cold weather and some may never cure if too cold for too long.

Capt. Hugh, What are the International part numbers for the grey and green fillers?

Capt Hugh, I asked the local Interlux sales rep about it and here is what he said;

"Yes we make Interfill 830 for heavy fairing (grey in color ) and Interfill 833, YAA813 Green Base / YAA815 Quick Dry curing agent is for very light final filling. This will sand easier but the Interfill must be sealed up with an epoxy primer whereas Watertite does not have to be primed."

Be careful, some epoxy stuff sands very hard... find a lightweight one.

Watertite is for finish filling, the others for heavy fairing.
The gray works great, and the green will get a surface almost perfect.
