DTM (Direct To Metal) primer offering excellent adhesion and sealing properties. Great for after media blasting or paint stripping.
Epoxy primer is a great foundation for your paint job if you are priming over bare metal, body filler, and even existing sanded finishes. Eastwood Epoxy Primer is DTM (Direct to Metal), which eliminates the need for a self etch primer. When thinned 20%, Eastwood epoxy primer makes a great sealer coat as well. Epoxy primer can be painted over, but is usually primed over with a build primer such as a urethane primer or ultra high build polyester primer.
Prep: Epoxy primer should be sprayed over a freshly media blasted surface or 180 - 400 Grit sanded surface to give proper adhesion.
Touchup or No Paint Gun?: Our 2K Aerospray cans are great for small projects and touchups where you don't want to drag out your gun and fire up the air compressor. You get the benefits of a true 2-part epoxy without the mess.
Existing Finishes: Epoxy primer is perfect for paint jobs over existing lacquer or enamel finishes. The epoxy primer will create a barrier to keep topcoats from reacting to your old paint. Sand existing finish with 180 - 440 Grit and shoot 2-3 coats of epoxy to seal away the old finish.
Self Etching Primer:
Traditional DTM primer where acid in the primer provides the extra bite to give you a solid layer to build on.
Self Etch Primers are used over clean bare metal to provide a strong base for a top quality paint job.
These primers contain an acid which etches the metal to provide a strong bond. Use self etch primers on steel, stainless steel, and aluminum panels. After applying self etch primer, you will typically follow up with a urethane primer to provide a high build surface which can then be block sanded smooth.
