PROCEDURE FOR CORRECTING RUNS AND SAGS
As with all polyurethanes Perfection should be applied in multiple thin coats. When applied in heavy coats, runs and sags may appear due to the thin nature of the coating. Generally it is best to start with the rubbing compound to try and correct the runs or sags, if the rubbing compound does not work
then proceed with sanding
. The following procedure has proven successful in correcting runs and sags within 48 hours after applying:
1) Sand smooth with 1200 working if need be to 600 grit wet or dry.
2) Use 3M™ 260L Finishing Film P1200 with Low Profile Finishing Disc Pad.
3) (Optional) For reduced compounding, use 3M Trizact™ Hookit™ II Foam Discs, Grade 3000.
4) 3M™ Perfect-It™ III Rubbing Compound with any Superbuff™ Compound Pad.
5) 3M™ Perfect-It™ III Machine Glaze with Perfect-It™ Foam Polishing Pad.
6) 3M™ Perfect-It™ III Finishing Glaze with Perfect-It™ DA Glazing Pad.
For more information on this system or products used please contact 3M™.
NOTE: Due to the change in the integrity of the paint
film which may take place as a result of this process, the buffed area may not maintain the same level of gloss as long as the remainder of the boat.
