It happens to everyone eventually. Whether you’re new to the hobby, or a veteran, fuzzy primer happens. In my case, I was priming from too far away. When you do that, the primer begins drying before it hits the model, and in turn leaves a fuzzy coat. I know better, but we all mess up.
Thankfully for me, the fuzzy areas are not in very obvious spots, the underside of the models. I tried to get a shot of it, but it’s really hard to show fuzzy primer on such a small scale, especially since it was minor in the grand scheme of things.
In this situation where the fuzziness is minor, and it’s not in a very obvious spot, I have a trick I like to use to fix it. You don’t need to strip the models. Here’s the magical weapon.
Yep, an old toothbrush. What I do is take the toothbrush and scrub the areas that have fuzzy primer. The process effectively buffs the area, and in turn smooths it out. Now, it’s not going to completely remove it, and make it perfect, but it will make a noticeable difference. How well it works will depend on just how built up the fuzziness is.
You can see the shiny spots now from where the toothbrush buffed the primer. If you wanted, you could go ahead and use a brush on primer in these areas to remove the glossy sheen to give you better adhesion for your base coat. I don’t typically bother. I find even buffed as it is, the primer still takes the base coat well enough, and I’ve never had any issues as a result.
That’s it. A really simple way to deal with fuzzy primer without having to strip your models.
