advice appreciated please: I want to dim the color of the front pockets on an aarn pack – being bright orange, not so good for hiding from sensitive trout.
The pack & pockets are silnylon. If I use a permanent texta to color them into neutral shade (e.g olive), what will the texta do the silnylon? Will it will affect the silicon treatment (probably)? More of a concern, will it damage the nylon?
