How to Repair Car Paint Damage : How to Scuff Old Clear Coat to Apply New Clear Coat


Hi, I’m Doug I work with 20 great guys in
St. Louis at Doug Jenkins Custom Hot Rods and we are going to do some work for your
today on Expert Village. As part of the chip repair you have to prepare the entire piece
for clear coat in order to that you scuff up the clear coat so the new clear cut would
stick to the old. This does not change the color of the piece. You are not damaging the
color this is only a superficial sanding so that the clear coat would stick. You can not
paint a shiny surface it has to be slightly dual. So he is using very fine sand paper
to rough up the surface in general. For the heavier repairs you use heavier sand paper
but when you are just scuffing up clear coat you use about 1000 grit sand paper. You not
trying to take any series kind of material off you are just trying to get it so it is
not so shiny any more. You want to be careful not to sand to aggressively on the corners
or you can go right through the clear and damage the color. Dan is being very careful
to just get thing scuff not to take any material off. After you have done your sanding of the
filler if you have done a really good job you want to use a little hard block or use
your thumb. You want it to be sanded nice and smooth like this. You should not be able
to feel anything, if you can feel something you have not done it right. It needs to be
nice and smooth it is very hard to fill a small chip like that not be able to feel it.

  1. prolly the most useful video of the 4 i've watched

    I wander if the pits on my hood from an egging would greatly benefit from this. most of them are through the clear coat and i know i can see shiny metal in a couple pits. I bet though that all the yoke splatter that has barely yet annoyingly spotted many areas of my clearcoat could be sanded away and looking like new with this technique…..how useful….thanks Doug. E-mail me with suggestions please
