M1A1HA Abrams

Gotta say I never primed unless I am doing a plane in a all metal finish....which has been 4 years since I put glue to one.

Welcome to the forums. I do the same as Dwight and Trevor, never prime. I hope you have a better molded kit than I did, my turret wasn't complete cast. Good luck.

Interior is a semi gloss white. Dials, knobs, etc. are a mixture of black and silver.

I have never primed any of my models and they have turned out fine. I do however prime all my photo etch parts.
I try to put together as much of the kit before painting.
Hope that helps.

Oh yea, and keep us posted on your M1A1

First of all, welcome to the forum.

Second, I have done the same kit previously. I assembled it without primer and painted it with Tamiya Dark Yellow (about 2 coats) without much problem on the fullness of the color.
Other modelers do priming so it boild down to personal preference. I can assure you however that even without priming, the kit could be painted in appropriate colors.
