Can you put body filler over rust?
There is no one definitive answer to this question. Depending on the type of body filler and the severity of rust, it may be possible to put it over rust. However, it is important to note that body filler should not be used if rust is present in the area where it will be applied, as this could lead to further damage.
Can you paint over pitted rust?
It depends on the rust. Pitted rust will not show through paint, but it may show through other materials. If the rust is very large or deep, it may need to be removed with a blacksmith's hammer and wire brush. If the rust is only small or superficial, it can be painted over with a light color and a thin coat of paint.
Can you paint over rust without primer?
Yes, you can paint over rust without primer. However, the paint will not stick as well to the rust and it will require more work to remove the rust.
Does rust stop if you paint over it?
Rust will stop if you paint over it, but it will not completely disappear.
How thick should body filler be applied?
There is no one-size-fits-all answer to this question, as the thickness of body filler will vary depending on the specific area being filler applied. Generally, body filler should be applied in a thin, even layer to avoid creating any undesired wrinkles or lines.
Auto body filler is a great option for rust. By using a high-quality filler, you can fix the surface rust quickly and easily. This will help improve the appearance of your car and make sure that it doesn't get worse over time.
