Really well actually. I have painted them in the past without it and it makes a huge difference. I have a Savage FV-SR 22LR that I use for small game and sling it and carry it through some brush and briars. That was probably 3 years ago and the finish is still really nice and held up very well.
Usually I'm not a big fan of 'Say it with Krylon', it was alright for the loaners from Uncle Sam way back when but you actually make it look good. Great job and thanks for showing us how the magic happens.
Here is another option for spray paint, there is a company Montana Cans that makes all kinds of webbing, crackling, different effects.
Pic is a little dark, lighting wasn’t very good in shop that night. This black web looks awesome on the Coyote color in dead weeds on edge of field
