Well joker,
I would figure out what paint product you are wanting to use first.
Then use their required K2 primer they recomend for their paint product.
Todays paint manufactures dont like standing behind their paint product when several types of other brands are used.

When something goes wrong in the paint process the first thing asked is what type products are underneath .
Then lies the BIG problem , they wont help you.

I will always stress that you need to stay with one manufactured product from start to finish! Never mix & match paint products.

I know alot of guys do it & have no problems , but they will scream bloody murder when something goes wrong & they have no clue what went wrong.
A word of advice you CAN NOT put lacquer base products over an enamel base product, but you can put enamel over lacquer.
