A: Hi Nick, You can sand this primer after waiting 24 hours. Reviewers have noted that the primer becomes rock hard after this time, though others found it may remain soft for several days if not mixed with a hardener and reducer as recommended.

A: Hello Booboo, yes, you can apply enamel paint to an oil-based primer so long as you allow the primer to properly and completely dry before application.

A: Majic Catalyst Hardener can be used with this paint.

A: For best results, I would recommend thinning Majic T&I Red Oxide Primer with Majic Reducer, #8-0750, (SKU: 117711999) at a ratio of approximately 10%, apply in thin coats and allow 24 hours to dry before applying additional coats of primer, or top-coating with a finish enamel.

A: This product is formulated to be used on iron, steel, aluminum, and properly primed galvanized metal, not fiberglass.

A: Majic Tractor, Truck & Implement Primers (Red Oxide, or Sandable Gray) are industrial oil/alkyd coatings that are designed for, and provide excellent adhesion & protection to ferrous metal surfaces – Not recommended for galvanized surfaces. To Paint galvanized panels with Majic T&I Enamels, galvanized surfaces must be cleaned and solvent wiped (to remove surface oils), etched/profiled with an acid based metal prep solution, then primed with an appropriate galvanized metal primer (non-cementitious), or a compatible self-etching primer, in accordance to manufacturer’s application & re-coat instructions.

A: Majic Tractor, Truck & Implement Primers and Enamels are high quality, hard-drying alkyds that exhibit excellent adhesion, corrosion resistance and protection to surfaces subjected to hard use, and harsh exposures… While Majic T&I Enamels are designed for use over Majic T&I Primers, painting either over a properly prepared epoxy primer should pose no problems (though adhesion testing is strongly recommended). The epoxy primer must be clean, dry and free of chalk, dirt, grease/oils, or other surface contaminants that may interfere with the adhesion of Majic T&I Products – and light sanding of the epoxy primer would be recommended to create a “profile” for a better, stronger, mechanical bond between 2 product films. Please carefully read, and follow, all label directions regarding application of Majic T&I Products, with special attention paid to the recommended applied thickness of each coating (thin applications @ 2.5 – 3.0 mils wet), and the allowable re-coat times for each (minimum 24 hours between coats). Too heavy an application, and/or re-coating too soon will result in a film that won’t dry “hard” for several days…or longer.

A: Because these are oil/alkyd products, it is always good practice to sand between coats with a very fine grit paper (recommended 350 grit), or fine Scotch Brite pad. Light sanding not only removes surface irregularities (such as dust that may have settled on the surface during drying), but also aids in inter-coat adhesion, and helps to maintain a uniform & consistent finish application.

A: To apply Majic T&I Red Oxide Primer by brush, first mix the contents of the gallon, thoroughly, until the product is a smooth and uniform consistency. Then, for best results, I would recommend thinning Majic T&I Red Oxide Primer with Majic Reducer, #8-0750, at a ratio of approximately 10%, apply in thin coats and allow 24 hours to dry before applying additional coats of primer, or top-coating with a finish enamel. The purpose for reduction is to help manage/control the recommended application thickness, and to aid in the “flow & leveling” of the applied film (too heavy an application, and/or re-coating too soon may result in a film that won’t dry “hard” for several days or longer).
