Ive got 3 litres of white 2k primer, i'm doing a very small bike panel thats going to be black, does anyone know if i can add some of the 1k black into the white primer to make a grey primer?
prob not, best to try an egg cup full with a splash of the black........ u'll soon know if it curdles....there are so many paint / chemical combination's.........perhaps save it for another job and get enough of the correct sort........u won't need much.....
