P118 Ultra 3L

Mipa P 118 Ultra PE-Leichtspachtel is a low-viscosity, self-levelling 2K polyester lightweight body filler designed to smooth out dents and surface irregularities during car body repairs. It delivers a pore-free, ultra-smooth surface finish that allows technicians to bypass applying a separate fine putty stage. Despite its lightweight formulation, it resists sagging and offers rapid curing with high-abrasion sandability.

Application & Processing Instructions

Substrate Preparation:

Thoroughly clean, dry, and degrease the surface with Mipa Silikonentferner prior to work.  

Sand the substrate slightly. Remove any uncured old paintwork or priming coats.  

Bare metal/rust repair: De-rust defective spots down to bare metal and dry-sand using P 80 / P 150 paper.  

Incompatibility:

Do not apply over thermoplastic paints or acid-curing wash primers (Reaktionsprimer).  

Non-Ferrous Metals & Restorations: When applying over non-ferrous metals (aluminium, galvanised steel) or during vintage car restorations, apply a primer coat of Mipa EP-Primer-Surfacer first to ensure optimal adhesion and long-term corrosion protection.  

Mixing

Mix 100 parts by weight of Mipa P 118 Ultra thoroughly with 2 parts by weight of Mipa Härter P.  

Do not exceed 3% hardener. Over- or under-dosing hardener can lead to spotting/bleed-through in the final paint finish.  

Environmental Conditions:

Process between +10 °C and up to 80% relative humidity with adequate air ventilation.  

Note: Polyester body fillers stop curing completely at temperatures below +10 °C.  

Sanding:

Body filler must only be dry sanded.  
Initial dry sanding: P 150 / P 240 grit paper.  
Final dry sanding: P 240 / P 320 grit paper to a matt finish prior to applying surfacer/primer coats.

Isolation:

Always isolate the cured filler with a Mipa 1K or 2K filler primer prior to topcoat application.
