For non-critical bonds you might substitute acetone. Glue: Zodiac #7097 Universal Glue. You can also use Avon Adhesive (one or two part) or Bostik® or other Hypalon or rubber glues.

It always leaves a neat tidy finish if you tape off the perimeter of the patch area with masking tape to avoid over glue. Mix accelerator and glue thoroughly either now or while waiting between the solvent wipes below. Accelerator is toxic; keep off skin. Keep mixed glue covered (foil or wax paper) when not using.

Pot life is about 1 hour. It may still look liquid, but will have lost effectiveness. Solvent Cleaning (2 times - to clean the fabric for a strong 'mechanical bond' with the glue) 4.

Scrub both sides (boat and patch or accessory) with MEK on a rag to clean surface. Wait 10 minutes after the first MEK wash. (time it) Mix glue and accelerator while waiting, if not done already. Apply one more solvent wipe with 10 minute waiting time (timed) between them.

Wipe off excess glue with solvent. If over 10 minutes or if glue has spots of white haze the glue has picked up moisture and you should try to 'reactivate' it. With a clean rag wet the glue surface with MEK but do not rub the glue off (one quick swipe). Then assemble immediately. For accessory on an inflated boat you can rub it down vigorously with a rag with MEK on it. Wait at least 48 hours before use.

Relative humidity must be less than 70%, preferably as low as 40%. Temperature 64° to 77°F. Note: You are using a two-part contact cement. The solvents in the glue must evaporate before assembly. When ready to assemble parts, the glue must not be tacky at all to the finger. It must not have spots of whitish glaze. If so, you may have spread the glue too thick, not waited long enough between coats, or a sudden drop in temperature or gust of humid air may have occurred.
