I tried something new today. For a while, I've been using just a brush to wet out cloth. I use it to brush on the epoxy, stipple it into the surface, then work out air bubbles. This works very well, but takes a LONG time and is hard on the wrists. I have arthritis, so things that are hard on the wrists are things I usually like to avoid. I've now gone back to the squeegee - it's much faster. The critical factor is using MEK to clean the squeegee. I avoided it in the past, and frustrating with vinegar, cider vinegar, and isopropyl alcohol led to me all-disposable products. MEK is a totally different story. I haven't figured out how to dispose of it in an eco-friendly way yet, so I'm reusing the same batch in a coffee can. You get some mileage out of it.
I may need a slower hardener mix, though. I've been on a 50/50 mix, and that has worked well because I usually dealt with small areas at a time. That was before I decided to peel-ply all of my layups. I had trouble getting it all wet out when I laid up the first of the two sides. I didn't want to just dump new epoxy on it to wet it out, since the stuff underneath was almost cured, so I may have a mix of peel-plied and non-peel-plied areas. I'll deal with it. One side is done; I'll do the other tomorrow.

Today I prepped the second side for its layup. I'm not installing the plans step so I skipped that section. I also pre-cut all of the cloth pieces, the peel ply, and so on.

This didn't take as long as I expected. I did a better job with the peel ply, although still not perfect, and I apparently still have a few bubbles. It takes time to get back into the swing of things. I'm not going to fix the bubbles now. I'll wait until I have more of the superstructure together, then one day I'll go around and inject epoxy into all of them at the same time.
The tub is done!
