Epoxy Safety
Avoid skin contact with resin, hardener or mixed epoxy. Wear liquid-proof gloves and adequate protective clothing to keep the epoxy off your skin.
Avoid eye contact with resin, hardener or mixed epoxy. Wear protective glasses. In case of contact with eyes, flush with water for 15 minutes and consult a physician.

I need to "shrink" a 1 9/16 inch inlet hole in an ancient ceramic urinal. I plan to use some kind of sleeve to form the new inside diameter. This sleeve will keep the G/Flex from flowing while it cures, but will then need to be removed. Is there something it will NOT stick to that I can use to hold the G/Flex in place while it cures?
JerryCPP
I use wax paper to keep G/Flex and epoxy from sticking to surfaces. Another possibility is to use a wax plug. Once the G/Flex has hardened a little heat will melt the wax.Dan
dlmellick
Hello, yes you can use bees wax or wax paper. Cheers
norskajarno1
Wax will do the trick. If you don't have a mold release wax, you can use a good, heavy application of carnauba or similar wax. The epoxy may have some adhesion to the item, but will become free with reasonable effort.

For bow building I will be building a bow oven. In making my own fiberglass laminations using G/FLEX, could this be heat cured?
yep
Not sure, here is the link to the West Systems G/flex data sheet:https://doc.jamestowndistributors.com/userportal/pdfs/WestSystem/West_System_G-Flex_Product_Instructions.pdf

Would I be able to use this to seal and essential repair small hairline cracks in a fiberglass shower tray. Thank you.
Ryan
Yes, that will work, abrade with 80 grit clean with acetone and apply.

What's the difference between 650-8 and 650-K?Trying to repair/weld an armrest where the plastic has broken from where the hinge ties the lid to the base. I need to replace the broken piece. (2004 Cadillac Deville).Will this hold the weight (at repaired hinge) of the lid when open? Lid weighs approximately 2.5 lbs.Thank you
Jugger
The 650-8 is just the resin and hardener, the 650-K it the whole kit with the filler and items pictured. If you are able to get a good bond, it should hold.

My Mustang conv. vinyl top has several small splits caused by stress at the fold points. Will this product work to seal and hold the cracks when the top is going up and down? Apply at what temperature?
Jim Morgenstern
I do not know the answer to this question. For quick repairs, the product worked very well on fiberglass.
CARL GOTTWALD
Thanks Charles. If and when it begins to leak, I will replace it, probably with a water-proof canvas product and flexes better over time. Jim
Jim Morgenstern
I don't think it's sufficiently flexible for a convertable top. Additionally, I don't know if it will bond to vinyl.
ROBERT LINDSAY
I doubt that this is the product that you want. While the epoxy is "flexible", that is a relative term, the cured product is very stiff. Many epoxies are hard and brittle when cured, G-FLEX is "tough" when cured and absorbs some shock with limited flexure, but what you want is a pliable bond, more like a silicone product. You might try a local upholsterer and see if they can recommend a fabric glue. I hope this helps some.
CHARLES WARD
What color does this product dry?
Bill Campos Jr.
Amber or honey like when dry
CRAIG PACINDA
My experience with this product a few years ago it dried to a very light opaque/milky cream color with a slight yellow tint.
Jeff Miller
Epoxy dries to a pale or light amber color.
JOHN REID
Clear yellow

will this plug a 1/4 inch hole in a polyethylene boat?
Tim Doe
Most likely yes. Flame treat the surface first and put a small patch on the inside and you'll likely be fine. This is amazing stuff.
CHRIS CONNOR
Hi Tim, Depends, it is fairly liquid and probably would not stay in the hole. Perhaps the thickened version would work but I have not used it. If you could some how get the hole horizontal and contain the G/flex so that it bonded on both sides then it may work. It is a very strong adhesive.
KERRY BEYELER
This is hands down the best epoxy I've ever used. If you properly prepare the surfaces it will fill gaps and it's very strong due to the fact that it's felixble. For patching a hole, you might want to incorporate some Fiberglas patches or plug one side and let it flow and settle. It does take at least 12 hours before you can even touch it, but after 24 it's very impressive.
ADAM BALKOVIC
I first started using G/Flex to cement neoprene shock mounts to plywood to fix my M-in-Law's 50-year old Eames Dining Chairs, and none of the repairs has failed. I have since used it for hanging metal tools like axes and hammer heads on wooden handles. Again, rock solid joins. I even rebuilt the handle of an Estwing masons hammer, replacing an inch long section of handle by using tape to create a cup on the end of the handle, and filling the cup with G/Flex which bonded securely to the metal core and flexible blue grip synthetic. Here is the caveat: I mix the G/flex in recycled PETE (polyethylene terephthalate food cups and after it is cured, the leftover skim of epoxy in the cup peels off in a thin sheet, leaving no cured product behind, so it does not bond to the mirror smooth PETE. I don't know if the PE in the boat will act the same way. After blending the resin and hardener I add west's 406 colloidal silica to the consistency of cake frosting so that it does not drip or run. If the through hole were slightly countersunk inboard and outboard an epoxy plug could be formed that would not easily push out of the hole. When cured it is easily filed and sanded to match surrounding contours; the color is creamy egg custard yellow. I say give the G/Flex a try. Even if it doesn't fix the boat, you will find uses for it around the shop, I am about ready to order my THIRD quart kit. If the epoxy does not work, perhaps P-Tex candle like that used for ski base repair might work.
CHARLES WARD
I use it to fill 1/2" holes in snowboards (I mount new hardware inside the boards) witch undergo a LOT of flex stress and it is unbreakable.
STEFANI HENDRY
will the product adhere to ABS ?
Debbie Dayringer
Yes, i had very good results repairing a roof rop cargo carrier made from ABS with this product. There are instructions with the product (and available online) regarding how to prepare the surfaces to be bonded. Be sure to get whatever fillers you need if any depending on your application. West Systems has instructions online.
KURT JABLONSKI
Yes, sand with 80 grit, flame treat, wipe with alcohol.

coverage of g-flex?
Undisclosed
Too long ago to remember. I only had a small area to repair and did not use all of the kit up.
LARRY WRIGHT
I used the G/flex system to seal the seams on a 14 foot row boat and still had a half of bottle left.

Will g flex bond to styrofoam to laun ?
Ron Lynch
Sorry Ron L, but I can't answer your question. I used the G/flex liquid epoxy on aluminum and it worked great.

Yes it will

this product is stronger than nails, I use G-flex to bond many different types of material, the extra dry time is a plus for me because i can take my time in the set up...if i need it to dry faster, i use a heat lamp to speed that process up...just a great epoxy

I actually used it on the back of an old window I am mosaicing. Two of the windows started to crack so I am trying this product on the back to stabilize the window. So far so good!! It was very easy to apply. I think I am going to put some on the front as well when I am finished and it is grouted. It will be outside as a view barrier all year so that will help preserve it. Thanks so much! Nancy

I used your epoxy with carbon fiber tow to repair high end composite hockey sticks. It successfully repaired blade damage, and broken shafts that have been holding up well!!!
