Ive searched all throught the forums and unless I missed something.......I cant find an answer. I've got an 07 gmc slt that used to have a really great looking matte leather interior. Over the past several yrs it just seems to have really developed a shine that I cant get rid of. Ive taken care of the leather since the truck was new and have used zymol, lexol, meguires and for the past yr Ive been using the pennicle 2 step. The leather is in good shape...it just has a shine to it! Its driving me crazy trying to get the leather back to matte!!! Is it even possible??? Thanks
