Hi Folks. Hoy do y'all deal will drips between layers of spraying nitro? I mean it has to be sanded flat right, but when do you do this... at the end after the cure or between sessions. If between sessions how long do you wait before sanding the drips out? Thanks. FTL |

Best to scrape off defects with a single edge razor blade, followed with gentle block sanding to blend the area. If its gooey -- its not dry enough. |

I would wait several says. Otherwise you will risk pulling it off down to bare wood and you may end up with a total strip of the finish. DAMHIK. I personally have had better luck with a hard sanding block and 220 g and then to something a little more fine when you get close. I find it a little less risky but scraping works well if the finish is well cured. You might try dialling back your gun a bit on the material. It makes life easier if you avoid runs and it's not that difficult. Couple of practice shots on a piece of cardboard is always good. Cheers! |

http://www.autogeek.net/meguiars-unigri ... block.html I've used that with a high degree of success...as has been noted, give it some drying time or else pay the price...and yeah, I learned that one the hard way |

When the run first happens (the surface is still wet) you can - lightly - place a piece of masking tape against it (holding the ends of the tape off the rest of the finish for the most part) and "pull" the run off the surface. A light spray over the area while things are still wet, can then help blend the area. Some sanding may still be required after things dry up a bit but removing the run allows quicker drying. Better to avoid them than fix them as has been mentioned. |
