Dear friends , i am a student from Poland , i am also working on this kind of coat BTW it's not a advertistment
This kind of coat can't work with car paint , i made many of tests if i could i will post a link to my youtube channel . For working we need to mat surfaces with sandpaper. Preparing just like for painting in paintshop. For this surface structure we need to modify a surface before application. Using this for fabric is no problem , i coated shoes , jeans , wood , concrete etc. Couple pics for you
This kind of coat is transparent , as you se on video ever dry , coat is a white, so if you want to cover black car paint you will have a white sedimentation. If you want know more feel free to ask.
