Mike's Montes has the "Correct" color for these interiors. I have been doing these for over 20 years and all the other products are either too Red or too Purple.
Of course you have to clean the upholstery first. Wax and grease remover, adhesion promoter spray, light coats of color, use a small stiff bristle brush and brush back and forth in between coats.
Let dry a day or 2. Then brush lightly again.
