Question:

how do i finish a metal door frame to prevent it from rusting.?

we have stripped a metal door frame so that the metal of the frame is bare. what CLEAR coat material can i use that will not turn the metal yellow (as a shellac or laquer would). what product can i use that is NOT waterbased...which would cause the steel to rust?

Answer:

Indoor or Outdoor? KBS Coatings makes a RustSeal in clear. It is a moisture-cured urethane that draws moisture out of the metal and atmosphere dries to a rock hard nonporous finish to completely stop rust. The Clear is UV sensitive and may yellow in time but not to the extreme of shellac or lacquer would. Clear can be topcoated with any opaque paint system to avoid this... or perhaps just choose Grey RustSeal. Bottom Line: If stopping rust is the priority, you need RustSeal on the bare metal to block its pores and seal it from moisture oxygen. The paint goes on in thin covering coats. An 8 oz. can will cover 12 sq.ft. with 2 coats.
oil based polyurethane
a clear coat epoxy, or a clear base D.T.M. (direct to metal) industrial enamel....painting contractor
you ought to employ a paint sprayer! mask off area, supply it some sunshine coats. a lot smoother end! you may also purchase spray paint in a can for metallic! it really is with out doubt one among the easist and best thanks to flow! solid success!
What about Rustolium the can spray. You may have to lacquer your frame, or just keep a wire brush handy. Good luck!
