THE STORY

Hi Tony,

Hope are doing well.

This is Ahmed , new Learn Auto Body VIP member from South Africa! 

I really enjoy watching your videos since I got tons of information. I have some experience in using a spray can but this is the first time that I will use spray gun &  I am waiting for my new ATOM-X20 LVLP Spray Gun  😇  I have 40-gallon or exactly 150 L air compressor /11.1 cfm /3 HP motor /8-9 bar max

I am working on my jeep Cherokee 1996 country, most of the clear coat is faded / clear coat peeling off so I decided to repaint the whole car.

I started to sand all damaged/faded surfaces with 120 grit and when I have removed the side mouldings in the doors I founded old bodywork, they have used body filler on rusted area, it’s not deep rust only in the surface but is not smooth even after sanding so I have removed 80% of the old body filler and in some area, I have reached to the bare metal using 80 grit.

Now I have several questions :

1) After cleaning all rusted area with 80 grit, should I use an epoxy primer first then body filler or it does not matter? see the attached photos to understand what type of rusted surface I mean. 

2) Can I use new body filler over old body filler ? As I said, I have removed 80% of the old body filler.

3) (The Main Question) What is the difference between the body filler & polyester putty? I bought polyester putty but I am confused because some guys said use polyester putty for tiny imperfections like glaze putty over the body filler.

4) Before applying the 2K primer what type of sanding should I use? Is 80-grit  enough or use 150-grit then 320-grit as a final sanding before the 2K primer?

Here are some photos for car in the attachments thanks in advance Tony!

Polyester Filler Primer or Polyester Glaze Putty

Feather fill G2 is meant to spray over a lot of body filler that’s cut and shaped with 60-80 grit. If you use this, I would spray over a 100 – 150 grit sanded surface.

Price: $80.00 – $90.00 a gallon kit.

Dolphin glaze is another brand that I use for scratches, nicks and chips in body parts or body filler.

Quick and easy to use, dries hard and fast. Sands great by dry or wet sanding.

Price: $15.00 on average.
