Guide Coat

Hi fellas, Dave Brockelmeyer here.
I have a question about what type of paint to use as a guide coat.
My definition of a guide coat is a contrasting color which is sprayed over primer then wet sanded to reveal any low areas.
I bought a spray can from Eastwood and it worked well but was like $14 per can.
I want to be able to use a cheap paint from WalMart if possible but am wary of what I apply and how it may affect my finish paint.
A friend once said it was OK to use any cheap paint as long as it was a light mist applied and it should be enamel.
I stopped at my local O'Rileys and noticed they sell automotive paint and asked about this.
He said to use a cheap laquer.
What do you recomend?
Thanks
Dave

I wanted to add that I am using Omni 2K primer and will be finishing with Omni base-coat/clear-coat

Hi

I always use a black paint. Just fog it on lightly. 3M makes a powder guide coat that works nice also.

Black is my color of choice but my question is: enamel or laquer? will either one have a bad reaction with the paint I am using?

It wont have a reaction because your just putting it on very lightly.

I agree with Mark, it is just dusted on and it should not have a problem. I would prefer lacquer because it will not clog your paper as bad as enamel.

Thanks , I appreciate the help.
