Just wondering, can I use Kodak Supra III paper for paper negatives. I have a shedload of this.
If you can, how do you do it.

Yep. Just do test strips to determine the optimum effective speed... you can partially pull out the darkslide, fire the shutter, full the darkslide further, fire the shutter again etc. and get a nice exposure test on one sheet. Then develop in RA4 as usual and... off you go. I'll take a wild guess and suggest the paper has an effective speed of around 20. So you could bracket your exposure test around that approximate value, i.e. anticipate that the optimal speed for you could be anywhere from, say, ISO 5 to ISO 40.
I don't recall whether this paper has a watermark. The Fuji does, which is annoying and means you can;t contact print the negs... unless you polish off the watermark or something. But anyway, you can get glorious color negs this way.
