Good epoxy. The best. However the cap assembly comes apart early on.

Adheres well


I found this adhesive pretty easy to apply when also using the Plexus mixing nozzle. I needed to re-adhere a broken closing handle to a plexiglass boat hatch. This adhesive has worked very well. It cured within an hour or so. The hatch closing handle gets a lot of stress on it and I see no indication that the handle bond is weak or lacks its original strength. A very good adhesive for plastic to plastic.

Bonds with Composite Hulls


I normally use with the applicator 'gun' and mixing tip on my Hunter ABS hull to correct cracks. Can be sanded to match smooth to finish although sometimes requires a fairing compound to get true. In my area where we have -10 to -20 winters and I cover but don't have any heated site for over wintering, cracks often appear in the same location each year. I blame this on the hull composition (Hunter has changed the 216 and 170 type models to fiberglass), not the product.

Outstanding product




You need other parts to best use this


This product is just the glue in tubes. You need to buy the pluger tool and nozzles seperately. Others sell this product wit a nozzle and plungers. I did not buythe nozzles. I squeezed equal amounts out of each tube and then mixed it with a stick and applied with a syringe. So you can get buy without it. The old product was more convenient.

Amazing Plastic Adhesive for Marine Use


Use it in difficult situations, especially bonding plastic/fiberglass to metal. Also very good for hull repairs. No real prep needed for site and works well even with moisture or oil contamination. Used it to repair 3 inch hole in hull of a Hunter composite sailboat along with fiberglass mesh. Easy to mix, sets relatively quickly but working time (approx 15 min) is adequate. Can be filed or sanded easily and can put boat back in water within the hour.While it is not cheap, it is the adhesive of choice for the really difficult bonding tasks or repairs.

This stuff is bomber!


Nothing bonds plastic to metal like this adhesive. Cures quickly. The smell will knock you for a loop. Use a good charcoal filter mask and nitrile gloves. Don't get it on you.
