Final Inspection and Topcoat Application

the bondo in one coat we're going to be two coating it it'll be covered 100 percent and two coats but once again um do you need to prime over your bondo no but if you're concerned about coverage then you'll want to spot prime it it's very simple easy to do do you need to sand after you spray that spot primer we spray the prop spot primer on and when i use the zinzer bin primer right here we never have to sand prior to doing our top coat this stuff lays out gels out absolutely fine if you do get some runs in it you'll have to sand out those runs so here's a look at the bondo glazing and spot putty we use just like this and i'm not in the automobile industry but it's my understanding that when you got large dents you put bondo over it sand that then you use bondo glazing putty to go over the top of that um if i'm wrong you can correct me but that's what's my theory is or what i've heard bondo glazing putty is it's widely used in uh the painting industry around here uh fixing nicks dings new construction all homes new construction they'll put spackle in all the nail holes sand that then you'll go over it with bondo glazing putty and you'll never ever see where that nail was before um before it was put there so this is it and i'm just got a few things i've got to bond on here and it's just swiped on with a knife goes on red dries extremely fast it's good for filling small things not good for filling large holes because it shrinks too much but great for getting rid of all these imperfections you can even get rid of brush strokes and stipple mark stipple marks by using bondo glazing putty but these little tiny nicks and dings you could never get rid of those with sparkle your sander would or sandpaper would sand those right out there's a spot right here where there was a latch and you'll see when i scrape it the dark areas what's left behind is where that latch was so when it comes to bondoing or actually priming over your bondo so the primer really is just for coverage issues so if you're losing low end top coats that don't cover very well that's really what spot priming over your bondo does it has nothing to do with adhesion i don't prime because adhesion the top coats we use adhere perfectly fine to the bondo so it's not for adhesion purposes it's just for coverage purposes when we're spot priming with bin bomb cans so there you have it a simple tip using
