POR-15 High Build Primer provides sandable and buildable coating that can be applied over dry POR-15 Rust Preventive Coating and allPOR-15 topcoat paints to enable quick refinishing and recoating of these products. For best adhesion on the Rust Preventive Coating, apply the primer when the Rust Preventive is dry to the touch but still slightly tacky (has a finger drag) or scuff cured Rust Preventive with 320 grit or scuff pad.POR-15 High Build Primer is a single component formula that fills in minor Imperfections. POR-15 High Build Sandable Primer adheres well to steel, aluminum, stainless steel, brass, and other primed and painted surfaces. This primer can be applied with a brush, roller, and sprayed with a 1.7 - 2.0 tip HVLP setup. If required, High Build Primer can be reduced with POR-15 Reducer up to 10%.

We developed this special "interlocking" primer after many requests from customers who wanted a coating with special adhesion characteristics that make it perfect for most painted surfaces, especially POR-15 Rust Preventive Coating.

This tie coat primer is highly resistant to penetrating topcoats, like lacquers, enamels, and two-component finishes. It sands very smoothly, as well. Try some of this sanding high build primer on your next project.

Just opened shipping box. No external damage.

But it seemed sealed from the inside….
Well, can leaked and I cant lift product out of box. It is now totally sealed all packaging inside and cannot even lift out to check where contents leaked from. I did not continue and now responding to a soution.
I can take a credit on my account and chose another product if that can be an option.
Thanks in advance. Keith Ellis. [****] (c).

Used to do the trunk work perfectly to this point and waiting for my liner to put in and my job will have been completed but it definitely stopped all the rest in his tracks

High build primer

The best high build primer I have used. Extremely durable also. Sands extremely well if you give proper curing time and use quality paper.”3m”
