Bondo Drying Time: Factors And Applications

Bondo’s drying time depends on environmental and application factors. Temperature and humidity can speed up or slow down the curing process. Thicker applications and slower catalysts take longer to dry. Bondo Body Filler is used to fill dents and holes, while Glazing & Spot Putty is for smoothing imperfections. Fiberglass Resin is for repairing fiberglass components. A catalyst initiates the chemical reaction that cures Bondo, which should be sanded before painting.
