TotalBoat434282 TotalFair Marine Epoxy Fairing Compound for Fiberglass, Wood, Aluminum and Steel (2 Pint Kit)

I have used this on multiple boats. First time application didn't work well, but that is on me as I didn't properly prep the surface before application. All other applications have gone great. This sands easy and fills where needed. Make sure you mix it well so that the color is uniform green! Otherwise it will not achieve maximum cure and hardness.

First let me say that I've never done fiberglass repair before buying this product. An accident resulted in a large crack that separated a section of fiberglass on our RV. After getting the fiberglass itself put back together from building it back up from the back side, I needed something easy to sand and paint for filling the crack on the visible side. This was what I decided to go with because of what appeared to be an easy to understand mixing and application process. The instructions seemed almost too simple - just mix it one to one and it's ready to use when it's green. It was so easy to mix and apply that I was honestly surprised. Sanding was easy as well, and it shaped up very nicely. It accepted the primer perfectly and made for a successful repair job. It has been six months since doing that project, and it still looks great with no signs of cracking. The RV repair shop who helped me with the mechanical damage from the accident couldn't believe that I actually repaired the fiberglass damage myself, lol.So anyway, while I can't recommend taking on a major repair project with no experience or professional supervision other than a couple of YouTube videos - that's exactly what I did, and this product is a big part of why I was able to do it. I recommend it 100%.

This stuff is easy to mix and mold to what you need. It stays workable for about 15min. Cleans up easy. Best buy for the money.

Product was delivered on time and worked well. It is a little hard to with. It's not bondo. The texture seems to run when applying it. I was working on rounded surfaces and it was probably more difficult. The materials blended great and dried solid in 24 hours. Easy to sand once cured. The containers don't seal right after use I don't know what's up with that? May be a one project and throw it away product.

I started a couple small repairs on my santacruz 27 and love this product. Its really nice to work with. It gives you adequate time for filling and shaping whatever you are doing and it's nice and smooth. Ive seen boat repairs done before and this seems to be the stuff you see mixed together and used. It must be the best stuff to use! I hope the small repairs last a very long time with this, I'm optimistic! Perfect thickness and dries within a good adequate time for shaping.

This is my second batch used in the restoration of a 23ft Jersey Beach Skiff. Compound is easy to mix, 1:1 ratio. Goes on smooth with the use of flexible plastic scrapers. Dry's to a sandable surface with in a few hours and I've been able paint over this compound within a few days. I've only used this on wood hull and deck surfaces and it's worked wonderfully to smooth out dings, gouges and some areas that had been over sanded leaving dish shaped depressions on the hull. Solid product!

Incredible for a floor repair in my RV

Used this compound to repair damaged fiberglass on an RV. Seemed worth a shot, and I'll say this I'd never go about it another way in the future! Holds like a champ, hardens like a rock. Be sure to carefully sand and clean your area quite a ways away from the damaged space. It will harden even in thicker spots, but it says not to over do it. It does start to get think after a few minutes even in cooler temps, I assume you can combat that by reduced hardener (not much though). Mixes easy, spreads a bit like bondo but seems easier to smooth out. Needs a wide tool to really get it smooth, and you just plan have to plan on sanding at least some because you'll never get it perfect before it starts to get stiff (unless your a professional cake decorator)!Overall, great product that probably has way more uses than the name and target market. No idea how it works on boats, but if my experience is any example I'm sure you can't go wrong.
