For nurgly greenstuff there's a few things that will help. Get some metal, not plastic sculpting tools from amazon. You will want something that makes dimples, something shaped like a trowel, something pointy, and something that looks like a spatula for smoothing edges down to the model so the transition is without a seam.

Keep your fingers and the tools damp. As greenstuff starts to dry it will pick up fingerprints or drag. Keeping surfaces damp ensures that you'll keep from ripping.

As greenstuff goes from freshly mixed to hard it slowly starts to harden, making it less pliable as time passes. This can work to your advantage but what I recommend is that you don't mix up a large chunk at once. Mix bits that are marble sized that you can deal with in about 5-10 minutes. If something looks great, stop messing with that spot and return to it in a couple hours after it sets up.

To make depressions, use the tool that looks like a round ball on the end of your tool. To make boils, find something with a nice round hole - I use different parts of pens that have been taken apart. You press down with the opening, making a raised round area with a depression around it, then you press down in a circle around your boil with the spatula tool, or other one for a different effect.

I also would practice before you touch up a knight or other large piece. That Rhino is a great idea. I have found some janky ones on Ebay that are perfect for corruption. I don't mind taking something that looks rough if the idea is to cover it with corruption. Grandfather is pleased with this.

If you're going to convert, take some time to google image search ideas, get a folder together. A herald bell I always thought was very cool on a Nurgle knight.

Greenstuff also makes their own tentacle maker. You could wing it with something home made but its not expensive and with a little practice you can make really great tendrils and corrugated tubes.

Any two-part epoxy with a smooth finish can work. Kneadatite from Polymeric Systems is what most people end up using; usually referred to as Greenstuff. You can order it online through Amazon or find it at most hobby stores that carry miniatures. I use Polymeric's QuikPlastik because it's cheaper and available at larger DIY stores. Milliput is also a popular choice.

Any way you go, be careful to mix it thoroughly and not to use too much. While you can trim it back with a sharp knife, it's easier to add more if you need to. You may also want to get some sculpting tools or dental picks to shape the putty and sculpt details into it. Then you can use it to repair damaged models, fill in gaps in larger metal pieces, and even to make custom parts.
