Best Overall: SEM Epoxy Primer over etching Primer

Buy on Amazon

Sem has been making feature-packed primer for years, thanks to a combination of clever design and high-end materials. This self-etching primer requires a top coat. It is a first-step coating that provides excellent adhesion to bare substrates. It lays flat, sprays evenly and will make the top coat application a breeze. The finish is a nice flat (almost satin) black with no fades or discoloration. It's also a good sealer base to spray a sandable filler primer under. The primer dries quickly (three thin coats five to ten minutes apart are recommended) and can have the color coats applied after only an hour or so. It is made for perfect preparation for paint. The paint will dry faster at higher temperatures.

• Covers very good and dries quickly
• Takes a lot to cover a surface adequately
• 80 °f temperatures without any problems

Next on the list, we've got yet another primer that manages to win our hearts. It's the sem etch primer and it's widely considered as primer that has the most suitable features. This is an amazing primer for bare metal. It is used to refinish some wheels and provides a good base coat for paint. It is mainly for bare metal. It is impossible to scratch it off with a fingernail or to have it lift off after peeling away masking tape.

This primer creates an abnormal amount of dust / overspray, but the adhesion is great. It is a professional grade self etching primer. The primer works, but the spray pattern + consistency makes it much easier to use. It will tell you the temperature range of the paint.

• Really adheres well to the metal barrettes
• Good investment for long term

Best For engine Paint: UPOL Epoxy Primer over etching Primer

Buy on Amazon

The upol epoxy primer over etching primer is capable of outshining several other primer featured in this list in overall features for the price point. This etch primer works very well as a base for raptor liner spray. It is perfectly, great stuff plus works well on bare aluminum (which usually surrounds the body filler, after repair is completed), so it's okay to spray over body filler where there is exposed metal surrounding the body filler.

This material is considered a thin material and the smaller tip works well with the 1.4 mm tip. It is only used over bare metal (which usually surrounds the body filler, after repair is completed), so it's okay to spray over body filler where there is exposed metal surrounding the body filler. It is nice that you do not have to sand before base-coating. It comes ready to spray. There is no need to use over only body filter, as urethane primer surfacer/filler adheres very well to sanded body filler without any type of adhesion promoter.

• Prevention from bedliner material adhesion for aluminum
• A must have sealer to spray down before bedlining
• Great product for aluminum jon boats
