    Worth the extra between regular box and Fatboy

    Posted by evorocket on Oct 21st 2012

    First, I need to establish this, these boxes are built to last. I have used the regular box model for over 20 years, until lately, I decided to upgrade to the Fatboy, for the 8" model. I use it for the first pass, for filling the joint. Being the filling coat, I used to have to do a lot more trips to the pump. The Fatboy model is worth the extra for the filling coat, wether you use the 8" or the 10" to do this. For the finishing coat, I use the 12" regular box, since it is a very thin coat. It is therefore lighter, and still requires very few trips to the pump.
