Ready or not, another Thursday has arrived, so let’s make it a good one. That means another week is almost over, and it’s time for Throwback Thursday. This week, I thought we would take a look back to March 2019. It was way back then that we filled you guys in on body fillers and bodywork.

The article, titled Painting 101: Understanding And Properly Using Body Fillers Get into the nitty-gritty details about a product that is either loved or loathed by enthusiasts. While many feel it’s a bad part of a proper restoration, others feel it is a great tool.

A body filler like Evercoat’s Metal-2-Metal, use a liquid hardener. Here, the products are being mixed on a tear-away sheet of a disposable mixing board. Never use cardboard to mix fillers.

We began or article by explaining how we will rate fillers on two factors—durability and workability. Durability refers to how well the product will hold up over time. Metal parts and panels can vibrate and flex. Over the years, areas repaired with filler might lift or crack. Filler staining is also something to consider. Staining is caused by a chemical reaction between the filler’s resin or hardener and the paint. This can be minimized by using a quality filler.

In the original article, we take a look at standard-, medium-, and premium-grade fillers. Something else you might not have known about fillers, is there are also single-step, fiberglass reinforced, carbon fiber, and metal-based fillers. However, you’ll have to check out the original article to learn all the details.

In the original article, we learn body fillers are rated by how well they turn to powder when sanded. The material that sands off should have the consistency of baby powder. It’s also a great way to know if the filler is fully hardened, as only cured filler will look like powder when sanded.

There is a lot more interesting and what might seem surprising information in the original article, and to learn more, you really need to check it out.
