Epoxy Primer - Epoxy primer is considered a good standard base when it comes to ensuring the auto paint bonds to the metal and promotes a quality paint finish. It's formulated specifically to prevent corrosion, so epoxy primer for cars won't sand as well as other types, like urethane primer.
Epoxy primer: a very durable primer. Has numerous advantages. Is extremely sticky and will adhere to nearly anything. I swear you could prime a fart or a rainbow with epoxy. I've used it over bare metal, body filler and after sanding smooth or applied in a highly reduced format, under color.
Old paint can be used as a primer. This content isn't available. When you need three coats, use any old paint that is left over from an earlier job as a primer. This works in almost all cases where the ``primer'' is a lighter color and can be covered and two more coats.
Epoxy Primer is another great DTM product. Epoxy primers is what it sounds like. This is basically a primer that is designed to be like an epoxy glue. On some jobs I have used a vinyl wash primer and then put epoxy primer on top.
DTM 1400 primer is a direct to metal corrosion resistant modified epoxy primer. Precision's DTM 1400 can be applied to provide a smooth high grade surface for finish coating with PC3, PC4 or PC5.
While there are a few etch primers that claim you can paint directly over them, it's generally not recommended.
Most replacement body panels are supplied coated in a good quality etching primer. There should be no need to remove this paint before painting.
A well-done paint job can breathe new life into a car, while a poorly done one might result in a rough and uneven appearance. Can you paint over primer without sanding the car? In general, it is not recommended to paint over primer without sanding the car first.
While etch primers may still have a place in certain applications, epoxy primers are generally considered the superior choice for most metal surface preparation needs.
On the other hand, Urethane is known for delivering a high-quality, glossy finish, making it a popular choice for premium applications like automotive painting. Its color retention is generally superior to acrylic, especially when exposed to UV radiation and other environmental factors.
You can use a primer to thoroughly cover the old color, then apply 1 or 2 coats of the new paint.
Yes, sanding the primer before painting a car is a step in the automotive painting process. This step ensures that the paint adheres properly to the surface and results in a smooth, professional finish.
Without primer, paint may not stick well to the car's body, leading to peeling or chipping over time. Protection – Primer acts as a protective layer for the car's metal body, helping to prevent rust and corrosion.
For example, if the paint is in good condition, you should be able to paint over it using a paint sprayer. First, apply primer or undercoat, let it dry, and then sand it in preparation for the base coat. Once the base coat has dried for about a half-hour, apply a second coat of paint.
You will want to use 2-3 coats of primer to ensure there is a good bond between the new paint and the wall, and also to cover up any previous colors, especially if they are red, orange, or a strange outdated color. In short, you will typically need 2 coats of primer for most painting projects.
In addition, water-based paint is preferred when covering an oil-based product because it has a faster drying time and resists fading in the sunlight for exterior applications.
In general, urethane primers are not as moisture tolerant as epoxy primers so the substrate must be dry prior to application. The exact limit is determined by the manufacturer. The cure time of urethane primers is often much faster than epoxy primers and have a slightly lower temperature minimum for application.

Can You Paint Directly Over Epoxy Primer? The answer is yes, provided that the epoxy primer has cured and the surface is dry.
Epoxy Primer – Epoxy primers are excellent for their durability, corrosion resistance, and strong adhesion. They work well on bare metal and existing paint, making them a good choice for cars with some rust or where you've had to do metal work.
After the primer dries, lightly sand away bumps and ridges using very fine grit sandpaper folded into quarters. When the grit of one section of sandpaper becomes covered with dust, switch to an unused section and continue. Wipe the wall clean with a damp towel or sponge and allow it to dry before painting.
If you have various stains, shellac Bonding primer is the ideal choice. It can be used to cover rough surfaces and old varnish as well as metal and ceramic.
After the primer has dried for 20 or 30 minutes, the tape can be removed. Although it's possible to go right ahead and sand the car (dry) and follow with the paint, it's a good idea to allow the primer to cure for several days, or even a couple of weeks if possible.
A quick sanding with an 80- or 100-grit paper is ideal for roughening painted surfaces that will be coated again, but a light sanding also does a great job refining bare steel. No need to sand all the way down through to bright steel, just go over the surface briefly and you'll be fine.
