TotalBoat Polyester Fairing Compound Customer Questions and Answers

7 of 7 Questions

Question

I was told that I could use this product above & below the water line. After applying the product and sanding, I could gelcoat over without any other steps needed. True or false? I turned the boat upside down to work on the bottom. I'm repairing along the keel of boat. Which is fiberglass and stainless steel. I also was told this product would work well over as long as I sanded first with 60-80 grit sand paper and then gel coated. Also could I just get more MEK? To count 14 drops for 1 once of compound. I've used a half bottle of MEK to 1/4 of a gallon of compound. Just working on the transom I replaced. I'm just confirming everything before I do all this work incorrectly. Thanks

We do sell more MEKP, but that seems like an awful lot of MEKP for 1/4 of a gallon of compound. Please call one of our techs at (800) 497-0010, it sounds like there are a lot of variables in what you are trying to achieve, and depending on the type of boat, keel, etc. When using this product, you can apply it a little shallow (by 1/16"-1/8") and before it has cured apply gelcoat over it to form a chemical bond with the gelcoat. Then wet sand and buff.

Hi, I recently bought some of this same stuff.before I applied I sanded with some 40 grit to get a rough profile.and yes you can directly gel coat over, that's what I did.  I would make sure you use good filling procedures and do more than a few thinner coats in lieu of one thicker.sand your final profile with 80 grit and gel away.I had no issues.

I would like to know if the polyester fairing compound is ok to use over dried laminating resin (with shredded mat) I used ? I made a repair above the water line and now need to fair and gelcoat. Thanks

Top Answer

Yes. For fine fairing applications such as small scratches or small cavities less than 1/8", sand the substrate with 100-180 grit sandpaper. For larger areas and deeper crevices more than 1/8" deep, sand the area with 60-80 grit sandpaper. Then remove all sanding residue.

Can this be used over epoxy?

Top Answer

You can use this product for light fairing over epoxy, but the surface must be abraded to give the Polyester Fairing Compound some 'tooth' to adhere to.

Question

My boat has an epoxy based paint surface, two part paint on it. There are some cracks in the paint, some chipping. Will this product work to fill and smooth the surface? How well does it stand up ? The hull is ferro-cement.

Asked on 04/04/2018 by Allen Harbor from North Kingstown

Top Answer

An epoxy based fairing material should be used to fix this problem. It is also more important to verify that it is just the paint failing and not caused by another issue. This Polyester Fairing Compound holds up great, but any fairing material, regardless of resin type needs to be protected from the UV.
