Hi, can somebody explain to me the process of glassing with one of these... can the gun apply the resin as well? or is this something you have to brush on or use a roller to apply, and if thats the case wouldn't all the chopped fg keep sticking to the roller / brush??? a how-to or a site that has more info would be greatly appreciated... the Saint

I've only ever used a brush. It's true, some strands of the matt sometimes cling to the brush a bit, and if you use too much of a sweeping motion, the mat moves around. A dabbing motion is best, and helps push out any air bubbles that may be underneath. As for the chop gun, beats the heck outta me. I guess I'm just old school. -------------

thanks, I appreciate it. since you've used it, would you recomend using that methos over the usual glassing methods, ie, hand laying the cloth? The Saint

Chop guns supply both the fiberglass and resin.

Chop guns only supply the fiberglass strands (roving), not the resin. Unless someone can point me to a gun that does both which would be cool.

I don't think the resin is applied at the same time as the glass. Unless the nozzle was discarded; the resin would cure and be very difficult to clean.
Chop guns are great for large projects, but are mainly used for high production, like hot tubs and small custom boats.
I have seen it done where the resin layer is applied to the surface, and then the chop gun shoots out and sticks to the resin, then it needs to be brushed on.
It is a great way to keep a unified application, but on a small project, it won't really help.
Best to stick with the brush and mat method.

actually there are quite a few set ups that apply the resin and glass at the same time, I found a few, but with more reading it just doesn't seem practical for my install shop regards, The Saint

I agree. I have used a chop gun that does both the glass and resin and it is sweet, BUT, it is hell to clean and is not worht it on small jobs, You have to use it on big jobs only. The guns are expensive also. ------------- Having Fun in Texas!

My bad, I stand corrected, then. Sorry to doubt you auex, I should have known better. Atleast I was on the right track with it being very difficult to clean!
To all of the members that have used one with both strand and resin, how do you clean it? Are the pieces removable and replaced? How do you get dried resin out of a tube or nozzle?

I have used a chop gun that does both a few times and the one a friend has at their FG shop is easy to clean.There really isn't much thcleaning the lines at you have to do.Everything is mixed in the air, so you have to worry about anthing harding in the line.The are very expensive and takes awhile to get used to also. My friend is always talking about how some of the guys get it to heavy in some areas and end up with uneven products.
