Why do we Prime

[Jim R]

Regarding rescribing seams lost during sanding, I’ve found it useful to rescribe the existing detail deeper as it gets eroded, and before it disappears.

Now that's a good idea. A tip worth noting

Very sound advice Barry. Regarding rescribing seams lost during sanding, I’ve found it useful to rescribe the existing detail deeper as it gets eroded, and before it disappears. That way you are not rescribing completely from scratch.

A good tip.

Many acrylic paints will just about fall off if a primer isn’t used.
