Due to the sealed environment of the Dynamic Mixing Nozzle, no air infiltrates the mixing of filler and hardener giving a high-quality finish.
By taking the applicator to the job and mixing "filler-on-demand", you don't lose what you don't use - and additionally, you save working time as you can re-apply filler-on-demand from the cartridge.
There's no scooping, mixing or cleaning up and a faster smoother finish means a final coat of filler or glaze could be eliminated. 3M's enclosed system ensures that your hands stay clean as well as your work area - giving an overall cleaner result!
Degrease the surface of and around the repair area - follow the recommendations of your paint manufacturer. Well suited for this step are 3M Panel Wipes 34567.
Recommended grids: P80 - P120 (or 150+ Cubitron II)
Tip: to prevent cross-contamination, always keep abrasives used on steel separate from those used on aluminium!
51002 - General Purpose Filler
51003 - Heavy General Purpose Filler for deeper dents and a slightly longer open time
51004 - Fine General Purpose Filler, smoothest to apply and sand, fastest to cure
51005 - Fine General Purpose Filler - Long. Smooth to apply and sand with a longer open time for larger areas / higher temperatures.
Recommended for all 3M fillers: use 2.5 - 3 turns from a previously set zero / closed position.
Advantages of DMS:
Usually 10 - 15 Mins at 21° - 24° C - can vary depending on filler used, temperature and size of the repair.
Apply 3M Dry Guide Coat to show the filler structure and allow a controlled fast sanding. Dry Guide Coat also helps to reduce clogging and extends the life of the abrasive.
Use 3M Abrasives 150+ Cubitron™ II by machine or with the right Handblock and dust extraction for a fast shaping of the filler area.
Re-apply 3M Dry Guide Coat to highlight any deeper scratches and surface imperfections to be removed with finer abrasives.
In order to prepare the surface for the primer application, reduce any scratches of 150+ by using grade 220+. To achieve optimal flattened results, use abrasive with a hand block.
The very last step before primer application then needs to be done with a DA machine and Cubitron™ II 220+.
To improve the adhesion of the primer, it is recommended to key the surrounding edge area with P400/P500.
