Foam Latex Patching
in General
How do you cook a pre-cooked appliance after you've patched with foam?
I've run a large foam latex appliance that has air bubbles and I'd like to patch them with a small batch of foam instead of pros-aide. I'm just not sure how to back the "patch dabs" of foam that sit on the already cooked appliance.
Would you cook the whole thing at a low temperature (120) for an hour or two? Would you hit the surface with a hair dryer for a little while? if so, how long? Can you think of another way to cook these small dabs of foam without damaging the already cooked appliance?
I know cabo-patch and pros-aide are common solutions but I like the sound of patching with actual foam better. I just can’t seem to find any info on how to cook the patched areas.
Thanks in advance for any ideas anyone can share.

This is not something I've done myself. The few times I've patched foam I just used pros aide and cabosil, which worked great.
In this video https://www.stanwinstonschool.com/tutorials/foam-fabrication-texturing-techniques-tutorial Ted Haines does some texturing techniques with small batches of foam latex that reminds me a bit of how one might patch a piece, though I can't recall if he baked the piece by popping it back into his oven or just using a heat gun.
Do you have any photos of the piece you are working on?

Baked it at 100 for about an hour to an hour and a half. Seems to have done the job. I think this only worked because my foam run was at about 4 and a half to 5 volumes so I could afford a little stiffening of the appliance through an additional bake. Not saying it actually did get firmer. I honestly can't tell. But I assume that's a possibility going in.
