I am going to vacuum bag a Carbon Fiber bar stool, using IN2 Resin, Soric and Carbon Fiber Tape at the edges of the Soric, like in the How To...Bonnet/Hood video. The stool will be like a 16-inch wide ribbon with a profile that looks like a "Z", and a Soric core. The total length is approximately 65-inches. I am in the US, and I cannot find Infusion Grade Spray Tack anywhere.

What method/s (other than Spray Tack) could I use to hold the Carbon Fiber Tape, Cloth, and Soric in place?

Many Thanks!

All resins and hardeners are a little different, so even if I remembered the exact numbers I used in these experiments they might not work well for other resins. (I used regular laminating resins and a really slow hardener with a higher viscosity than infusion resins).

If anyone wants to try this out, take several small airtight screw cap glasses, put 10 grams of resin in each container, and then add 2, 4, 6 and 8% of hardener or whatever numbers you feel might work. Then leave the mixtures alone for at least a day, maybe longer. Since there is no exotherm the curing reaction will take much longer to complete. Check the samples for goo/tack factor by poking them with a stick. They should be nearly solid. Dissolve some in acetone and apply by spraying.

If for example the 6% works fine, more hardener can be added to the 2 and 4% experiments so they aren't wasted.

If anyone tries this out, please post your results.
