What is the difference between 1k and 2k primer
1K paint has a faster drying time compared to 2K paint and will air dry.
This means that the paint does not require an activator to dry, unlike the 2K/Pack alternative.
1K/Pack spray paints are ready to spray without activation of the self-contained 2K hardener found in the base of the aerosol can..
Can I spray epoxy primer over etch primer
It’s fine to spray epoxy over self etching. But self etching is mainly to slow down rust before you lay down your filler or other high build primers. If you do have a rust issue I would start by eliminating the rust issue ahead of time. Self etching primer may slow down the process of rust but it will not stop it.
Do you rub down primer before paint
Primer is pourus, as long as you let it harden properly and thoroughly dry it afterwards it should be fine, I always wet flat between stages when I’m using rattle cans. Btw I’d go with at least 800-1000 before top coat personally mate. That way you’ll get a really smooth surface ready for basecoat.
What is the purpose of self etching primer
Rust-Oleum Automotive Self Etching Primer promotes maximum adhesion and smoothness of the top coat on bare metal, aluminum and fiberglass surfaces. Etches and primes in 1 easy step. Rust preventive for a long-lasting finish.
What is the difference between primer and etch primer
Regular primers are used on organic materials, while self-etching surfaces are used on metallic surfaces where rust needs to be prevented, and strong adhesion between the surface and the paint is paramount. …
Do you have to prime over self etching primer
Epoxy primers Self-etching primers have to have another primer over the top of them or the paint won’t adhere. It can’t be an epoxy primer, but it can be a urethane primer. In the meantime, it’s important to talk to your paint dealer about the time window allowed between the primer and paint topcoat.
Do I need etch primer on bare metal
The first step in painting metal is to thoroughly clean it. The metal might look and feel clean, but any grease, oil, dirt, or rust left on there will prevent the paint from properly adhering to the surface. … Self-etching primer is ideal for painting metal and creates the foundation needed to bond with the paint.
What is the difference between self etching primer and epoxy primer
Self etching primer bonds well to bare metal surfaces and can be top coated in a short period of time. Epoxy primer can be applied in heavy coats which can be guide coated and block sanded to remove small imperfections in the body. Epoxy primer takes longer to dry (cure) before it can be sanded or top coated.
Can you paint directly over etch primer
You can’t paint directly over etch primer. You need a surfacer or other primer/sealer over it. … You need to use self-etching primer to paint aluminum, but prep work is especially important. You have to sand the aluminum first, with 120-grit sandpaper.

As long as you let the primer fully cure and then scuff the surface it will be fine. As a matter of FACT body filler works better when applied over a protective primer (epoxy or self etching) simply because the primer helps protect the bare steel from moisture.
What is best primer for bare metal
Epoxy primerEpoxy primer works best on bare metal and is recommended for newly-fabricated metal parts or those that have been fully stripped. You can also apply primer surfacer or filler over epoxy primer to get rid of any minor imperfections and to create a flat surface before you paint.
What happens if you paint metal without primer
Without the use of a primer, in many cases, oxidation will begin leading to rust and the eventual decay of the metal. In addition, the chemical makeup of paint is less binding than primer meaning it will flake off easier without a primer underneath it.
What’s the best primer for bare metal
epoxy primersTwo-part epoxy primers go one step further by including zinc phosphate, which increases its corrosion-inhibiting properties. Simply put, epoxy is the best primer for bare metal, making it excellent for newly fabricated metal parts or ones that have been fully stripped.
