Metallic and activator questions

I'm kind of wondering about two different subjects but jammed them into one thread.
First regards metallic and reducer. Do you want to use a slower(closer to temperature reducer) so the metallic can lay down or a quicker reducer so it stands up?

B: Basecoat activator: Specifically for Chromabase. One of my paint suppliers feels the activator is unneccessary, which is what I was taught 20 years ago when I started mixing it at a parts store. i was told to sell them reducer with the base and nothing else was necessary for the basecoat. I just read a tech sheet on Chromabase and it suggests an activator, I brought this up to the two DuPont suppliers locally and they said they never were told about it even at DuPont school. Wouldn't the activator be necessary to help adhesion of base to substrate and clear to base? This in addition to making the base actually cure rather than just dry out and be sandwiched between primer and activated clear.

Thanks in advance,
Chip.

Reducer, what you say seems like common sense but depending on the metallic you are spraying and the charge it has, using a fast can in certain colors kill the charge and the metallic will never lay right, usually this is most noticeable in the blend part of the paint job.
Use the slow as the paint will be easier to lay more even as far as metallic orientation.

Activator also helps big time for the laying of metallic.

A funny note, the warranty guide I have from them says for a approved or certified shop to qualify for warranty the base must be activated.
I have had it (warranty) a couple of years so not totally up to date but sounds like someone was not paying attention in class but they know their stuff, not me.

I was hoping you'd reply on this as I trust your opinion more than the parts guy with a mixing bank.
