there are many instances in which using filler or bondo over a painted surface
is very acceptable and in this video I'm going to talk a little bit about that
and I'm going to give you some tips on how to go about it so that fixing hail
damage ice damage or small dings can be a lot easier before I begin however I'd
like to demonstrate how well filler sticks to just a DA'd surface or a
sanded oem painted surface as compared to a grinded service - this is fully cured
bondo and I'm just going to take an air hammer to both sides so that you can see
how well it sticks so it did chip off right here and it didn't chip off here
and even if I take up a chisel to that that sticks very well and that sticks
very well so to me it sticks very similar to both surfaces so you can rest
assured that your filler is going to stick to a properly sanded painted
surface the first step in using filler over a painted surface is to sand the
area so I'm going to be using 120 on a DA and I'm going to take care of this
little ding right here
and that's good enough right there I'm just gonna get the rest of that with my
finger and some sandpaper I'm gonna mix up some filler and I'll be right back
the next step is to mix yourself up some body filler and we're just going to
spread it - after mixing and applying the
filler the next step is to use a cheese grater to take off the excess that way
you're not tempted to use a rougher sandpaper and end up putting steep
scratches in the paint so we're just going to gently run this across there
and just take off the excess so that we can use 80 grit or even
100 grit on this and then we'll have a nice smooth unscratched
surface to prime over so when I get this cheese graded and it hardens a
little bit more, I'll be back to sand it - after using the cheese grater
the next step is to use some 80 grit or a hundred grit and you're just going to
lightly go over it because the cheese grater got it almost almost right on
and now it's it's super close it's down to 80 grit but I'd like it a little bit
smoother too before i prime so what I'm gonna do is just use a DA with some so
this is just this is 120 and I'm just going to go over this very lightly
and that little ding has been taken care of without grinding it down to bare
metal so if you had hail damage and you had these little dings all over the hood
this would be the way to repair it I hope you enjoyed this video on whether
