On fiberglass boat in high humidity cure time ?

I use Nu Finish twice a year on my fiberglass ski boat. It should be applied in the shade and at 3 sq foot areas at a time. Excellent results. One suggestion: use a Fiberglas de-oxidizer first if the fiberglass has dulled with age. The Nu-Finish does a great job of preserving it like new.

My understanding is NO. This is superb for repair of even fairly large holes/tears in aluminum boats but does require some drying/curing time. It does set rather quickly and is very tough when completely dry. Really doubt its effectiveness on wood. Underwater...NO....

I have only used it on a dry surface, but in the comment section, I saw a this: By CaptJack on January 14, 2013 Verified PurchaseThis stuff has been around for years....... and it works. I keep a kit on the boat. Weather the white or the gray it will always stick and harden. I have used it under water and on water jackets with 100% confidence. Once hardened you can file it and even drill and tap it. For emergency repairs and long term renovations I trust it.

Sorry I have not tried it on fiberglass but I think the 3m stripe off wheel is safer.

I live on a lake and fly mine off water all the time. In the first week I burned up the receiver and motor when it got very wet. Replaced the parts and treated the receiver/esc and motor with CorrosionX. That stuff is amazing. It will waterproof the components and is a good lubricant for the motor. goes on like a thin oil. Just squirt it on (try and work onto both sides of the receiver/esc board). With this treatment the plane has survived dozens of "not so good" landings on water. Re-apply every 20-30 water landings. Google the stuff, modelers swear by it.

Waite at least one hour. I this on a 45 foot motor yacht to kill mold and odor.

As long as the surface of the boat is free of pits and scratches you can apply the film and not worry. Any blemishes or roughness will make applying the film very difficult and will probably not last long.

The KeelShield can be re applied after it has been cleaned and the mating surface is clean. It does take 7 days for the 5200 to cure fully. It works great even for boats in salt water with the 5200. I have used the 5200 even for below grade seals at 9ft below water. Big key is ensure surfaces are both clean.

In a boat bilge with a fan blowing and applying 70% solvent coatings: about a half hour before mild breakthrough. Very much worth it. Once outside the bilge to change cartridges, it is evident even after breakthrough, I was still protected by these noxious vapors.

No...it's not for fiberglass, it's for porcelain tubs. Try googling 'fiberglass tub repair.'

Yes Maryanne, use the clear Flex Seal. Make sure surface is fully dry, and outdoor temp is above 60 deg F.

yes within the limits of its strength. it won't hold pressurized water or air forever (plumbing or scuba). i would give it 48 hours or so to cure. the crucial point, as with all adhesives, is proper lamination. the surfaces to be glued must be strong and clean. good luck.

It's the heat .Too warm .Needs to be s cool environment to cure ,if you use a blow dryer in a cool setting would speed up the process .

I'm assuming you are asking about a gelcoat finish on fiberglass . If so, I would recommend 3M Marine Restorer and Wax as it's designed for gelcoat.

No, it will not. It just helps to repel water, dirt and other staining items from the deck. Also helps with oxidation on the fiberglass throughout the boat.

Yes this is good too repair anything fiberglass.Although if it just just a small crack i would just buy the fiberglass resin and cover the crack with a couple thin coats of the resin and it will seal it up

I would not expect the repair to last. Your boat probably flexes at the point of the crack and this otherwise excellent epoxy probably would not hold as it would flex at a different rate. You really need something like Bondo fiberglass repair with a fiberglass cloth patch, in my opinion.
