My local auto paint supply house no longer sells the DU-5 activator for the PPG Concept paints. They sell the DCX-61 activator. If I use the DCX-61, is there any difference in the paint for being resistant to raw fuel?

Thanks - Steve

DCX-61 is the correct one to use now. Mix it just like the spec chart calls for. I mix it 4 paint 2 reducer 1 hardner.

I have used bo0th activators and the paint still stands up to 30% Coolpower.
