Speaking from experience of not using it, (haven't gotten my can of accelerator yet) It is possible without it. Patience will be necessary (I don't have much of it

) You'll have to make sure and let each application of CA dry for a couple minutes at least to be certain it's dry before putting the next one. The accelerator makes that waiting into seconds instead of minutes. It also prevents there from being any sticky spots that might grab the paper towel from you and cause a few choice words to be spoken, or screamed

It isn't necessary to have the accelerator, but my firsthand experience means i wont finish another call with CA until I get it. (I have some on a fed ex truck in Ohio right now, should be in by the weekend lol) It's not incredibly easy to get even thickness of CA across the whole call (for me), which means sanding through it in some places accidentally, and I think it'll be easier to control using the accelerator. I am in the process of typing up all of my notes from the last couple weeks on CA to let KC take a look at, add to, edit, and then post on here for everyone to hopefully learn from some more of my mistakes and failures

My intent is to have that finished and to KC by the weekend.
