If you want even a more rich look, I would suggest using the UK-11 instead of KBC-11.
Using the UK....
When you spray candy red over a silver metallic, the first couple coats will be pinkish looking. So it will be up to you to keep putting on more coats until you get the nice deep rich candy red look.
I can't tell you how many coats to apply because all painters have different spray techniques.
A painter could even have that look within 2-3 coats, but I think most will take 4-5 coats, maybe even 6 coats.
As far as the sealer, you can use one that would be best fit for the metallic you plan on using. When we use the BC Silver, we mix the black and white together (KS-11 and KS-10) to give us a gray sealer.
The new system coming out will have a gray sealer that is really nice to us. Better than the KS sealers!!!!
Look for the HOK complete line coming out soon!!!
