priming and filling question

Hi Folks. Once you've primed a section and noticed maybe some chips to repair, do you sand the area back to styrene or can you apply filler OVER the layer of primer?

Cheers

Depends on the filler - with Apoxie Paste, I just apply over the primer

This is an excellent question, and I'd like to see other people's take on this.

For minor stuff, you can use a "Spot and Glaze" putty. You can find it at automotive stores. It comes in a tube and is usually red in color. It's actually made for use on primer.

For major stuff, you might have to sand down to the styrene and do more puttying. I'd really try to avoid this if possible. What I do after puttying and sanding is this; I hold the model up to the light where I'm looking at it edge on. You can usually spot flaws that way.

You want to prime when the surface is smooth to the touch and imperfections are not visible otherwise. Holding it to the light is a good way to check.

What say you?

I usually just use the Spot Putty right over the primer with no problems.
