I came across your site by chance with the help of Google. I want your opinion regarding when I use an imagine from a magazine (which is glossy)I want to know what your expert opinion is to seal my finished product without ruining the magazine part of the mixed media project. I want to be able, if possible to use the products on most of the project. I use gel medium for my go to glue at all times, but not sure it is what I should use on the top of glossy magazine papers. Any multiple ideas or suggestions would be a great help to me.
Using gel medium is usually fine on a glossy magazine image, but it you've found that other images from the same magazine smear (test an unimportant one first), then I would recommend spraying it first with Krylon acrylic spray. Several light coats are better than one heavy one. Krylon comes in both matte and glossy finishes, so make sure you get the right one for your purposes.
Here is a tutorial for how to use gel medium to make an image transfer with a glossy picture, in case that look might appeal to you for a future project.
