This is my first try on using top coat. The thing is, after I applied topcoat, the paint/ink can still be rubbed off >< then I applied another layer, the result is abit better, but paint/ink can still be rubbed. If u look closely u can see my fingerprints. FYI, i'm only using GM01 fine line marker cos i have limited resource.
I'm guessing I applied insufficient topcoat or I didn't wait long enuf for it to fully dry. wat do u guys think? I watched at gunpla tut and it said topcoat will be dried like for an hour only...but I let it dried for the whole afternoon

so I'm guessing I applied insufficient topcoat. please correct me if i'm wrong.
btw, wat i did is shading or weathering? i'm confuse wif those two
