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. Now Dan is sanding with 800 grits sand paper to remove the last
little traces of the repair. He filled it originally with polyester body filler. That
did a good job filling the majority of the defect. The last of the little defect that
he fills with, actually just a first coat of paint using it like a primer. It fills
the little line around the repair left by the body filler. Since Dan did not introduce
any new contentments he was just able to wipe it down with the tact rag and get it clean
again. Now we are going to for another coat of the base maroon color just to fill up the
little bit of sanding that he just did. We are just trying to make sure that we got good
coverage over the repair area. There is not little lines showing and no sand scratches
showing. The paint acts like a filler for that.

  1. from an ex- body- paint person, you're 100% correct.

    Any imperfections by improper prep will eventually become visible in the top coat… although hidden for now. As the volatile organic compounds escape from the paint, the paint surface gradually conforms to the substrate underneath. The paint continues to cure for months, so the paint film loses some thickness, and WILL conform to what's beneath. The prep has to be perfect if the repair is to have perfect, permanent results.
