Why It Matters
Structure & Shape
Start Here
The wrong filler, mixing board, or seam sealer can crack, sink, or telegraph through paint months after delivery. Top shops standardize their body fillers, glazes, and seam sealers so every tech gets predictable sandability and long-term stability.
From spreaders and mixing boards to panel adhesives and seam sealers, matching products to OEM procedures keeps your repairs strong and OEM-compliant.
Sandability
Quality fillers and glazes sand clean without clogging paper, saving time on every panel.
Shape Retention
Correct hardeners and mix ratios keep repairs from shrinking or sinking after delivery.
OEM Compliance
Modern panel bond and seam sealers are designed around OEM procedures and crash performance.
Rework Rate
Standardized materials and mixing practices drastically reduce cracking, pinholes, and come-backs.

Body Repair Tips
01
Mix by Weight or Ratio
Too much or too little hardener changes cure and shrink. Use consistent ribbon length or mix by weight for your body fillers so every batch sands and cures the same.
Filler Accuracy
02
Glaze Over, Don’t Rebuild
Use putty and glaze only for minor imperfections and pinholes. Large low spots should be corrected with filler — overbuilding glaze leads to cracking and shrink-back.
Glaze Usage
03
Follow Seam Sealer Windows
OEM procedures specify when to apply seam sealer relative to primer and topcoat. Following those windows ensures adhesion and long-term corrosion protection.
