the quickest trick to using the MM Acrylic primers is to add some Future to your mix,or try some Golden Medium, # GAC 200
another way is to give your model a coat of straight Future, sand it with steel wool (to scratch it up), wash it clean, then spray a thin coat of MM primer over that
I just did a side by side by side test with MM primer over Future coat, MM+Future mix, and MM + Golden,all three stood up to the “burnished Blue tape” rip off adhesion test
I still like the Vallejo large bottle gray primer mixed with Golden 200 better, though
i go to ace hardware and use the NOW cans at < $3.00US for a big can. us eit to check seams and as a primer for acrylics. have had no problems until i get near the bottom and it gets a tad powdery. just shake it well and use that part of the can for armor. crack a new can for boats and planes.
Hokey the times I tried M M white and gray primers they just did not cover right. Did every thing as usual washed the model and stirred the primers.
Tarn Ship again thanks for the pointers,and I do use total acrylics switched years ago keeps the wife quiet about the smell and I can paint when I want don’t have to worry if the grandkids are coming over.
one thing about Vallejo that I always forget to add,there is a “primer” color in their little bottles,that is a paint that is the color of primer, maybe something to use when painting a body panel on an old half finished Hot Rod car
the real primers are in larger bottles,and come in many colors
