Hey guys I am new to the forums, though I have been lurking for a while now learning a lot. Got myself a new PVC dinghy and did the much easier sharpie method I learned here. Came out great and looks amazing, though I rolled it back up cause I am going to use it every weekend and just take it on my small car so it needs to be rolled up, there is Sharpie smudges everywhere... Did I use the wrong sharpie or something? cause I doubt it.
