<p>Metal grills face harsh sun, rain, dust, and sometimes salty sea breeze. If the surface is left bare or the coating cracks, rust quickly starts eating into the bars and spoils the look of the elevation. A good primer and top coat seal the metal, slow down corrosion, and make it easier to wipe away dirt. Regular touch-ups with suitable window grill colour paint keep the structure strong and the windows looking well cared for.</p>
