Installing KERF BUBBLE SEAL

Question

How soft is the kerf part?  Is it difficult to push kerf into window groove?  Do you recommend using any installation tool that will not tear or cut the bubble seal?

I don't think you'll have any problem just pressing the kerf to lock it into the frame; the bubble should hold up fine, and there shouldn't be any need to be too aggressive here. Just be sure to clean out the groove before installing it.
