Actually, I'm pretty sold on Rockhard for small plaster repairs. It's a
gypsum-based mix anyway. It's convenient but expensive compared with a 50
lb. bag of plaster patch. It doesn't shrink on small repairs that I've ever
noticed.

And if you mix the powder with latex paint, you get a darn good nailhole and
dent putty that won't ghost through your finish paint. The only problem is
that it sets up pretty quick when you mix it with paint and if you're too
sloppy and let it cure too long it can be a pain to sand down.

Also, I've found that mixing the Rockhard with latex paint makes it pretty
waterproof and good for minor fillings like nailholes and small gouges. I
keep meaning to do a Consumer Reports type test where I take a piece of beat
up scrap lumber, fill the various gouges with the Rockhard-paint mix, finish
paint it, and throw it up on my roof for a few months.

Wow! I just had a thought! What about mixing Rockhard with parrot guano? Now
there's a solution for those pesky limestone steps! Heck, maybe I'll just
feed the Rockhard to the parrot. It's probably better for him than Captain
Crunch.
