Would this "polyester"-based resin be okay to repair fiberglass on fulcrum of a diving board or would I be better off spending 10x more on "epoxy"?

The real answer would be what you want to accomplish. Structure repair, or cosmetic? I personally would use resin designed for maritime use. Check the data sheet for the 422 to be sure it has some elasticity. Additionally, 422 is primarily for automotive designed to get its UV protection via paint or an opaque gelcoat. This stuff is great and I use it but if not protected it turns yellow and brittle. My "go to" composite repair for composite structural repairs is carbon fiber and epoxy.

I'm not a diver,and have only used this product on water filter O-Rings, but I can't imagine there being a better or cheaper product to preserve/lubricate/ rubber that is exposed to water......and a little bit goes a looooong way. I would recommend trying it, and at worst you'd have a less expense product for maintenance and storage of your gear...I believe it'd make an excellent seal though......and regarding deterioration of the rubber/silicone mask, silicone grease should be the lesser of other petroleum evils.

It would most likely stick to the fiberglass, but it is not really meant to get/stay wet. I'd probably try Bondo instead.

I would recommend a silicon sealer when installing this item; also my application through hull on my fiberglass boat was no problem; There is adequate allowance for the thickness of any vehicle auto or marine; Just make sure that the surface is not curved when the hole is drilled in order to avoid slippage and any potential leak.

Yes, It would be a good choice for fiberglass Kayak repair in my opinion. It is felxible and strong. I used it to repair a Carbon Fiber bike frame for that reason. I have used it for repair of Fiberglass rowing shells as well. You may want to check the West System web site for other options just in case ther is a better choice. They make great products.

Absolutely. POR-15 is fully compatible with fiberglass and can be used to repair cracks in gelcoat. It will adhere better than polyester resin and has greater strength. Use also with fiberglass cloth to make super-strong surfaces in rusted-out areas. But be aware that POR-15 doesn't contain styrene and thus cannot melt fiberglass cloth like polyester resin does.

We have the item listed below but not available on Amazon: A unique combination of marine silicone and polyurethane, formulated especially for fiberglass. LifeSeal offers a fast-curing, low odor, high adhesion, non-sagging, non-corrosive, non-yellowing formula. It provides a durable permanent watertight seal for joints subject to structural movement. LifeSeal sealants may be used above and below the waterline. Use for sealing decks to hulls, thru-hull fittings, vinyl ports, sealing/glazing windshields and bedding marine hardware. Will adhere to metal, glass, wood, Lexan, ABS and certain other materials. LifeSeal can be removed without damaging gel-coat. Not recommended for ferro cement hulls, impregnated wood or oil-soaked materials. Cures in presence of water. Mildew resistant and acid free. Color: CLEAR CARTRIDGE, Part#1169 Thank you for contacting the Bottom Paint Store.

I haven't tried the product on fiberglass, but so long as its not a transparent type glass I would assume it to be okay. If it were the transparent glass you might only try a small corner first to insure the product does not scar the glass or permanently damage it.

Yes more than likely. I have on my boat and the adhesive is auto grade. I cleaned really well with alcohol before I placed on the Fiberglass. I even placed an unhooked up strip under my swim platform to see how well it would stay and still there after a season of boating. You might be able to remove with a blow dryer from paint but not sure.

I'm not sure I'm qualified in this case, because I have only used this epoxy for small projects, but I think this would not be an appropriate adhesive for a project like that - epoxy is super good at filling spaces and cures very hard, but it is extremely brittle once cured, and I would not think that an area which will be frequently wet would be great over the long term. This is such a specific thing that it might be worth emailing the manufacturer, just in case I'm wrong!

I used this on a steel boat tank. My tank needed a repaint so I did not need to be careful. It did not seem to peel paint that it got on. I would not want to get it on good paint though, as it is very tenacious and not easily removed. I do not know how it would effect a plastic or fiberglass tank. It can be painted once dry and seems to be holding up well. Mike

Tough thing with epoxy resins is that it flows. The fiberglass cloth, if used properly, can help to control this. Once dry the only way to deal with run off is by sanding. of course this will produce a rough finish. Smooth the finish by using Acetone solvent applied liberally with a q-tip. several attempts may be required. If the fiberglass cloth is exposed then another application of the epoxy resin will be required.

It would seem to me that you could do this. I found that the clear coat does not go as far as the epoxy does in coverage. You may need additional clear coat.

The general specific gravity of cured epoxy resin is about 1.3. It is heavier than water and will not float. You could include some air bubbles in the casting to achieve more displacement. There are agents like Cabosil that you can add to lower the SG, but they will effect the transparency.

Hi Doug, I'm pretty certain it won't hurt the fiberglass in any way. The problem will be to have the stains exposed to a solution of super ironout for a long enough period of time for it to work completely. I principally use it to clean iron stains off of mineral specimens. I soak the specimens in a warm super ironout solution from 2 hours to overnight, depending. Good luck, Steve C.

Never tried it for that application. Would think Gorilla Epoxy would work. Epoxy will hold most everything with a few exceptions.

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.
