Why am i wasting money on primer

[durangod]

I have noticed many times that just normal handeling of model parts leads to both the paint and primer coming off. So why am i wasting money on primer at all?

I don't know. Why are you wasting money on primer? I've mentioned numerous time I rarely prime my kits. When I do feel like putting a primer coat on, I usually use Rustoleum 2X grey primer.

That is exactly what i use.

I normally only prime metal and resin parts, and entire models only if they have a lot of those or if I intend to spray them with a water-based acrylic (like Vallejo or Ammo) for the first coat. When putting Tamiya or Mr. Aqueous paint over plastic, I've never found a need for primer at all.
