This is the second one for me. The other was in 2007. The 07 lasted about 6 months but by the time it was finished it kicked ass. I've been in business for 15 years and in my industry for 30 years. I use Devillbiss Waterfalls along with Ceramic Ball Traps. I tend to over-smear tools because I hate making mistakes. Ever since I've been in the fiberglass repair industry, I've been using these types of tools for hours on a regular basis. This came out after 5 months. When I contacted the seller they said they couldn't help me and I was told to contact the manufacturer. Hutchins was lecturing me on water issues, blah blah blah. I had time to ship it under warranty but added expensive tools to my stack that don't stand up to the real work. I went back to the Ingersoll Rand copy from the Dura block. They last about a year and I can buy four of them for the price of a Hutchins.
