I have a used Badger chink pump for sale. It can hold up to 15 gallons of chink in the hopper (but I only put in 10 gallons at a time). It comes with 30' of 3/4" high pressure hose, an applicator gun and 4 tips. Its all metal construction and built to last.

It makes chinking faster and easier, and chink is definitely cheaper when you buy it in 5 gallon pails. Use it for your chink job and sell it to someone else when you're done with it or do some bartering for chink work. Send me an email if you're interested at geobuildit@yahoo.com. I'd be happy to deliver if you're not too far away and share what I know about chinking.
