When Can You Tape, Sand and Buff? Booth Bake vs Garage Air-Dry
Same 2K clear, two clocks. Baked in a booth at 140Β°F: 30β40 minutes, and once it's cooled you can tape, cut and buff. Air-dried in a garage at about 70Β°F: tape after about 16 hours, cut and buff after a day, full cure in about a week. AutofxMart's free Cure & Bake Schedule gives the flash, recoat, tape, cut-and-buff and full-cure times for seven coatings, air-dry, force-dry or infrared.

DTM Primer Sealer: 4:1:1 or 4:1:2? (Valspar DTM2004, by the Sheet)
DTM primer sealer: Valspar's DTM2004 is a direct-to-metal primer β onto steel, aluminum or galvanized, properly cleaned and sanded β and the same can is the sealer. The gallon's own label says "DTM Surfacer/Sealer". Valspar's data sheet settles it with one digit: 4:1:1 by volume (4 parts DTM2004, 1 part DTMA activator, 1 part reducer) is the primer surfacer; 4:1:2 is the primer sealer. That one extra part of reducer changes everything after it: 1 to 3 medium wet coats become 1 to 2, flash drops from 10β15 minutes to 5β10, solids by volume go from 40β50% to 30β40%, and only the sealer can be topcoated without sanding, 8 hours max.

DTM primer or sealer? It's the same can #shorts
Primer or sealer? Valspar's DTM2004 is both, and its label says so: DTM Surfacer/Sealer. Valspar's own data sheet: 4:1:1 by volume is the primer surfacer; 4:1:2, one more part of reducer, is the sealer. Let the sealer flash dull 5β10 minutes between coats, and topcoat in 20β30 minutes with no sanding for up to 8 hours.

Bare Metal: Etch or Epoxy Primer? (By the Sheet)
Bare metal, and four cans that all say primer. Here's which one goes on it, from the makers' own data sheets (U-POL, SEM, High Teck, Transtar, SprayMax, USC): etch primer leaves 0.6 of a mil and takes colour in 30 minutes; 2K epoxy is the one whose sheet names a time for body filler over it (1 hour at 70 Β°F) and stays recoatable without sanding for 72 hours; high build is 2 to 4 mils and exists to bury sand scratches; and "sealer" is often not a fourth can at all β it's the high build or the epoxy, thinned. Four names, three jobs.

P80, 150, 180, 240: skip one and the scratches stay #Shorts
P80, then 150, 180, 240. Skip one, and the next grit can't take out the last one's scratches. A plastic bumper? A red scuff pad by hand, never coarse paper, then plastic prep and adhesion promoter. Clear coat? All wet: P1200 only on runs, then 1500 and 2000, up to 5000 before you polish. The free Grit Selector gives the order for your job and your surface; the whole tool is the full video on this channel. Next up: the Mixing Calculator. Follow so you don't miss it.
