I'll take your word for it ,i have done the floppy and one of the drives with paint and i shoved them back in the case (very carefully loll) they have been sittin there for 3 to 4 days now,i'll try the clear coat sometimes this week see if it sticks
Thnx for the tip

Update: i've tried it on a piece that i painted around the same time, it was very dry but did the same greyish thing. Maybe the clear coat was too strong (not of the same make)
It's ok , it looks good anyway
