After market metal parts and paints

[NAMBiohazard]

Hi to all

I was wonder what is the best way to prepare PE parts and metal barrels for paint.
Cause no matter what I do mine keeps flaking before I even finish the kit
The only aftermarket parts that seems to hold paint is metal tracks

Im kinda new to pe and metal parts myself. But ive seen guys like coen just lightly sand their metal parts to get the paint to stick better. Also do you use primer? Sorry im not much help but I thought I'd try

I like using metal barrels for my tanks, and I usually rub it down lightly with 2000 grit sandpaper(dry) to give it a rough texture for the paint to stick to. For PE I do the same, but you have to be careful around raised details. And finally, I use a gray primer to cover the entire model.

Hope this helped at least a little bit.

Hi guys

Thx for the responses
I use for metal part usually Humbrol No.1 (primer)

But will try out the sanding as I usually just wash the model after construction with alcohol.
