Hi everybody . I am the owner of Albin Vega " Kirsikka" Number 3139 built in 1976 which is in South Finland now. I need to do some gelcoat reparation works on the hull due to some scratches. I need to find the right tone of white for the gelcoat in order to make it look exactly like the original but I am a bit lost here. Is there any way to know what where the factory -chosen colors for each model? Is somebody or some company kkeping track or files about it? if not, is there any other known thechnique to find the right tone? Thanks!!!!
