How Long After Applying Auto Body Filler Should You Sand It?

[MilaLynn]

Under normal circumstances, with uniform filler thickness and favorable weather conditions, the drying time for auto body filler is approximately 2 days before sanding can commence. The actual drying duration depends on the thickness of the filler application - excessive filler usage due to uneven surfaces will correspondingly extend drying time. Weather conditions also play a significant role; sunny days with higher temperatures accelerate the drying process. Additional information: 1. After applying auto body filler, a waiting period of 1-3 days is required before painting: The suitability for painting depends entirely on the filler's dryness level. Premature painting over incompletely dried filler will likely cause peeling issues later. 2. Longevity of auto body filler: Automotive filler doesn't last permanently. Typically, it maintains integrity for about 3 years, sometimes less before showing signs of peeling. The durability significantly depends on the application technique and workmanship quality.
