GMC Sierra HD detailing in Houston

What we watch for

Paint and interior on the Sierra HD

Paint and exterior

Tall flat doors and a towering hood make swirls obvious on dark trucks. Diesel soot settles on the tailgate and rear bumper, and a gooseneck hitch leaves rust-colored grime that stains a spray-in liner.

Interior

Pro and SLE trucks use vinyl or cloth with rubber floors that rinse well. Denali HD cabins have perforated leather, and the tall step and wide sills take the most dirt from work boots.

Living in Houston

An HD that tows a boat to Galveston comes back with salt film and tar on the lower panels. Washing the salt off within a few days keeps it out of the hitch and the chrome.

• Tows and hauls: hitch, rear bumper and the lower panels collect road tar and brake dust, so they get iron remover and tar remover.
• Pickup bed: tell us what the bed carries; spray-in liners clean up well, drop-in liners come out for the rinse.
• Hard clear coat: swirls take more cutting to remove, so correction is slower, but a corrected finish holds up well afterwards.
• Lots of chrome: Houston hard water etches it, so it is dried fully, polished where needed and sealed.
• Large wheels and tall tires: wheel faces, barrels and wells take real time on this one, and it shows when they are done right.
• Rubber floors and drain plugs on some trims: easy to rinse, but the seams still need brushing to get the grit out.
