My frame should be home from the sand blasters this weekend. What methods work the best for you? I need a gallon of the metal ready, and a quart or POR15 rust preventative, right? Do I brush it on? sponge brush it on? does it all have to be done at once? Or can I do it over several days? Any particular time of day? Any help at all would be great.

Don't use the sponge type brushes. They break up in the POR 15 then leave the pieces stuck to your work.

A regular bristled bush works great.

I bought one of their 6 packs of Por-15 and did almost my whole frame and the rear end. I might be able to finish up the frame with what I have left, but there are areas I can't get to because the body is on, so I'm not counting those. You may need more paint.

You can do the job over several days. I did my frame in 2 parts about 6 months apart. You should, however, do all your coats on an area in one session. The first coat needs to be tacky but not dry.

As for time of day, I think POR specifies a temperature range for applying the paint. I forget where I read it but it was somewhere. I didn't follow it. I've painted in the dead of winter and in the heat of summer so I don't think it matters that much.

When I did mine, I used 1 gallon of Metal Ready and a Quart of Semi-gloss black. I brushed the entire outside of my frame and I had plenty of extra. If you wanted to you could try to do the inside and have enough. Power washed my frame after it returned from the sandblaster. This removed the leftover sand and dust. I then sprayed it with Metal Ready twice rinsed and let it dry. I slightly flashed with rust and then I painted it with the POR. I did all of the painting at once. It took only a few hours.

Don't forget about painting the areas where there would be a chance of sun hitting it; as I'm sure you're aware, the POR-15 is not UV resistant and will start looking crappy (I think it turns it white-ish)...I ordered a gallon of marine clean, a gallon of metal ready, a quart of Semi POR-15 and 1 pint of chassis black (for the areas where the sun will hit); oh yeah, got some of that 'new metal' stuff (looks like cast metal)...lots of $, but so far the stuff works good...

Cheap paint brushes work the best on regular POR-15, but you want to use a foam brush on that 'new metal' stuff (per their directions) and that doesn't need a top coat...a little bit goes a long way and don't apply it too thick...you want to put on at least two coats, drying in between...I've only done the front part of the frame with two coats and also painted part of my brake/clutch pedals as well and there's still alot left! I plan on also painting the radiator shroud and many suspension components with the POR-15/paint as well...I am only going to be doing the parts of frame I can get to with the body on...I am pretty sure I can get all of that with the one quart; but the true test ;)

It goes on real nice, but I have had bad luck with stuff finding it's way onto the surface as it dries (in the POR-15)...I tried straining it and it helped, but still there...almost looks like little dirt specs...the good thing is 400 grit paper takes it off and prepares for the next applications...I would recommend practice on smaller pieces first imo...
