TotalBoat Marine Gelcoat for Fiberglass Repairs - White Quart, No Wax

I like TotalBoat fiberglass products. Each seems to work perfectly, as advertised, and this gel coat worked great!

Could not have renovated a sailboat that went through Hurricane Michael, without this stuff. The biggest complaint I have heard in the past is that gel coat that is not molded onto fiberglass does not adhere well. My boat was completely bare of polish or wax, and pre-sanded with 220/400/600/1000/ and 1500, because my existing gelcoat was in horrible condition. Took more sanding at the coarser level, and very little at the fine, finishing level. Don't know about a boat with wax, but I did find if I inadvertently dropped a drop on virtually anything, this stuff adheres to the point I can't remove it, plastic, cement, stainless steel etc. I got the no-wax because I have an older boat and did not want a standout shiny patch. Having said that, I would speculate that a pure plastic (then coated with wax after drying) would be stronger than a plastic mixed with a foreign material like wax. There is an art to using gelcoat over epoxy and filler. If you are not a skilled sander you may have trouble. I put on with a paint brush quickly in a space surrounded by painters tape. I also did a few less drops of MEK than was recommended which extended my dry time, but also "working" time. Then I removed the tape even before it dried, because when I had let it dry, it pulled up the edges of the gelcoat paint job. Started with 160 sandpaper and went to 400 for final finish--all wet sanding only. Takes patience, and you have to be careful around the edges where the old finish is. This stuff is dynamite on non-sked surfaces. Did not even have to get rid of the dead gelcoat--just cleaned with soap and water. Used a high quality paint brush that I had to toss after each application, and worked quickly. Non-skid has two sets of lines--one down and to the right, the other ninety degrees off and to the left. I brushed on to the right and finish brushed into the other set of lines to the left. Makes a more uniform looking surface. Hard as nails and stain free thus far. Sealed with several coats of Star-brite marine polish. Looks brand new. And, almost forgot, had to tape around each non-stick surface to make it look professional, when applying.

Be aware that Gelcoat without wax should be your first coat and requires Gelcoat with wax as your final coat. And they really recommend five coats total which can be sanded to a polished finish It's Labor intense 💪 and must be applied in the recommended temperatures two part mix catalyst included mix in half quart batches for easier yields and 1 quart just about makes it on a 19ft Hull not including transome and must be thoroughly cleaned with Denatured Alcohol... Do not clean surfaces with Acetone.... Use Acetone for end clean up and tools.. Apply with 3/8 roller it can be sanded after final coat to a polished finish use Gelcoat with wax for filling in small cracks and gouges sand, then clean with denatured alcohol then apply Gelcoat without wax as first coat . finalize with Gelcoat with Wax for final coat... I sanded down 15 years of anti-fowl paint down past the gel coat in spots with 60 grit. DA sander then worked my way up to 220 grit Then applied three coats of gelcoat... great product overall extremely hard finish. Looks like a brand new Hull I used the 3/8 roller that was recommended but I think if you use a half inch on final coat and then sand to a polished finish starting with 180 to 220 grit, you can bring it up to a thousand grit or wet sand it.... I didn't bother. It looks great with 3/8 nap roller considering it's the bottom of the boat

I don’t want to just say that gel coat is gel coat. This appears to be a good quality gelcoat that adheres very well and sands very well. It’s a pretty bright white so just don’t be surprised if it’s brighter than what you need.

So far so good used it for repairs with out wax then added wax from there web site for last coat. No problems at 50 degree My very first experience with gel coat seems quality, valuable, good coverage, seem durability, drys good when used correctly

Good product, fair price but can be tricky to use.

What I have to say is, this gel coat comes through every time. I sands great, is out performs any other gel on Amazon. I made the mistake of trying a different brand and got burned. It didn’t sand well, ate up most of my sand paper, even my 40 grit airfile paper gummed up. So don’t be fooled, this is the only gel I’ll ever use again and I’ve been doing boats, gel coat and fiberglass repair for 40 years.

Great product

Worked for what i wanted some patches on boat bottom. Its hard to mix make certain you have ab eye dropper or something to measure drops if using a small quantity

Will never deal with them again. Very high prices (double the price compared to other brands) very poor customer service. And the delivery date took way too long than expected.

Good price, was enroute but lost in transit. Canceled order but vendor handled the matter with class.
