I could have swore I saw a post with your dye to water ratio. Guess I was wrong.so here is what i did and it fixed the spots....my original schedule was:
I am diluting transtint with DNA, not water.
But here's what i did to fix the situation. instead of sanding the washcoat, i just left it dry and then spay the stain right on it. i believe that when i sanded 320 the washcoat, i was sanding off the washcoat making it pointless..i dont know if this theory is correct but i did notice a more even finish by not sanding the washcoat and go directly to spray stain
