As I have no bodywork experience, I wonder if it's standard to completely cover the body with filler, then sand it down (as seen on many of the Velocity Channel restoration shows) before applying primer and color coats? Obviously this amount of hand crafting is not done during initial manufacturing, but is there an advantage to this? Seems a high build sealing primer would make this unnecessary.

This would be my basic method, but I haven't painted a whole car in almost 10 years.
http://www.914world.com/bbs2/index.php?sho...p;#entry1045953 Strip paint, blast etc... Flatten dents, welds etc. Two part PPG epoxy primer Fiberglass bondo on welds Finish dents with regular bondo, only as needed. Two part PPG epoxy primer (1 coat) High build primer and final block sand Seal with two part PPG epoxy primer (1 coat), this is actually the first coat of my topcoats. Top coats. High build primer is a paint used to fill minor imperfections during block sanding, never try to use it as a bondo filler. |

I'm pretty sure the high build primer we use is a type of epoxy primer so the additional coats of epoxy are not nesassary. A sealer is not always needed, especially if you are using all materials from the same product line. There are also DTM - direct to metal, fillers available. |

A sealer is not always needed, especially if you are using all materials from the same product line. There are also DTM - direct to metal, fillers available. I think you're right and I imagine tech has changed, but I always felt I had best result laying down a coat of epoxy before the filler. I'd use the short strand FG bondo for welds, as it would seal a missed pinhole, just a skim then regular bondo on top of it. Sealer for the top coat depended on colour, yellow needed a sealer as it's terrible for coverage. I believe the yellow primer on my bug (link) was a primer/sealer. I personally never used guide coats, I'd just pick different colours of regular and high build primers. Once I began a job nothing touched the surface that wasn't a 2 part product. Some of this is like a brand of oil or gasket sealant, every painter has favorites and stick with what has worked well for them in the past. |
