Hello all, I'm pretty new at collecting comics but nearly 50 years at reading them. So I had an unopened, artist's proof near perfect (to me) Rick and Morty #1 variant with the lenticular cover that was my first submission for grading. My first mistake was sending it in unopened. I assumed it being unopened would help show how new and untainted the book was. Well, it was rejected. Turns out there is a sticky residue on the edges of the comic where they glued the lenticular cover onto the book.
Otherwise I'm thinking this book is great for grading and the census shows only 4 other books, 3 at 9.8 and 1 at 9.6. Should I attempt to clean the edges of the sticky residue and re-submit it? Should I send it out to be cleaned by a third party? If I clean it what's the best way to remove that residue?
