Prime time test shots.

Test shots done with certain hobby paint primers.

Results: Mr. Surfacer 1200, NO graininess coat of paint.
Bright Touch GP Primer, Some graininess noticed.
Mr. Surfacer 500, much graininess noticed.

Conclusion: My choice is Mr. Surfacer 1200 for model priming paint.

Further conclusion: I don't mind paying extra for what I want and don't have to worry about some "significant other" (wife) questioning or yelling at me about my spending habits! Those days are long gone and in the dust bin.

Thank you.
