Okay so not technically modelling I know but there's a few DIYers on here I am sure so worth a shot.
I have a resin bow thats covered in mold lines and I would like to get rid of them. My brother-in-law had given me some wet/dry sandpaper of varying grades and said to sand it out from coarsest to finest. I have started doing this and it has worked on the test bit but also made the colour paler. As I keep going with the different grades will this polish itself out and return to normal colour or am I going to have to do something to cover it up?
