The 5 Best car Filler primers (2023 reviews)

Duplicolor car filler primer is the epitome of what a great primer should be. This stuff has got strong vapors. It's a general purpose primer. It sprays on smooth and after sanding it doesn't gum up the sandpaper as much. It does well and lays down really nicely. It is great for 3D print post-production to get around hours of sanding.

The primer is also a filler, and everything but the deep gouges fill nicely, the black covered and adhered nicely, as did the clear coat. It is easy to use and gives you a good base on which to apply your final color. The dry time is typical and sanding is EASY. This doesn’t take a lot of sanding after the first coat either.

Why We Like This:

Does a great job dries fast and sands easily
Great primer that fixes any small scratches in a few coats
Very good coverage over flaked paint after it is stabilized

Best For Bare Metal: Evercoat car Filler Primer

Next on the list, we've got yet another primer that manages to win our hearts. It's the evercoat car filler primer and it's widely considered as primer that has the most suitable features. This is the next best thing to coating an entire rough panel in plastic filler. It's basically a sprayable plastic filler and it does a very nice job of sealing off wood grain, rough fiberglass, and very rough body work if you need it to. It cleans easily with acetone to add to that will get hard and brittle. It is designed to be sprayed in conditions from about 65 degrees to 100 degrees. If the paper is too fine, it will clog easily, especially if you are not wet sanding.

It's a pack of tubes with clear liquid. It is great as part of the finishing process. It is basically a sprayable plastic filler and it does a very nice job of sealing off wood grain, rough fiberglass, and very rough body work if you need it to.
