SEM Self Etching Primer - 20oz Aerosol Can - Black

Why you'll want it

• Grips prepped steel, aluminum and stainless. It is formulated to bite into properly prepped metal. The record lists excellent adhesion to steel, aluminum, and stainless steel.
• Dries fast to keep the job moving. The quick drying formula lets you move on to topcoating sooner than standard primers. Less waiting means more of your project gets done in one session.
• Helps resist corrosion. It builds a base that resists corrosion, and the record says it holds up to marine and automotive projects.
• Prep metal this fall for spring. Fall haul-out and winter storage are a good time to prep and prime steel, aluminum, or stainless steel parts, so the topcoat can go on when the boat returns to the water in spring.

What it is

SEM Self Etching Primer is a black spray primer made by SEM and sold in a 20oz aerosol can. The record says it is designed for properly prepped steel, aluminum, and stainless steel before topcoating. The record does not explain what self etching means, so this copy does not define it.

How to use it

1. Apply to properly prepped steel, aluminum, or stainless steel surfaces for good adhesion.
2. Spray straight from the can.
3. Topcoat once the primer has dried.

What else the job needs

Good to have on hand: a topcoat, since the record describes this primer as applied before topcoating. No additional items are specified in the product description.
