I add shortening to my fondant and it seems quite maleable but whenever I squeeze the gun it leaves little indentions. I recently made pencils for a cake and there was a small line about every inch or so. I know I'm just a perfectionist and others were complimentary but those lines bothered me and I always want to learn how to do everything better. Would love to have input from those of you who use this tool regularly. Thanks so much.

Before I extrude, I microwave the piece just a little (under 10 seconds). Then I coat it quickly with a small amount of Wilton glycerin...this works so, so well!

If the piece has tylose in it, no matter what I do prior, it comes out funky, so in this case I extrude the piece larger than what I need, then roll on parchment paper with my fondant smoother...again, this works really well!

I only use MMF, by the way.

Those indentations are from where you stop squeezing and start squeezing again. Try not to squeeze so hard. Because your fondant is SO malleable, it practically flies out of the gun while you're squeezing. When you stop squeezing, it comes to an abrupt stop, causing the indentations.

Yes, I do use Tylose in the fondant to get it to harden, especially for the pencils. I'm sure I probably do squeeze too hard. My husband is always having to replace the faucets because I turn them off too hard. I will try less pressure and maybe the glycerin next time. Thanks again for taking time to answer.
