Bare metal flares, the rest of the body is painted
So the question is for bare metal. Order options 1) epoxy primer, bondo, high fill primer, sealer, paint, clear OR 2) bondo, high fill primer, sealer, paint, clear What would you suggest? And, given my lack of a paint booth, I will have a paint shop do whatever stage I need to ensure no bugs land on the paint. I will paint and bodywork up till it must be a clean room process. I need some advice on the steps and order. Rich |

My only concern with option 1 is that the epoxy primer be sanded if it is allowed to completely cure prior to filler application. There's generally a recommended window where the filler can be applied without sanding, but after full cure, it probably should be sanded prior to ANYTHING being applied on top.
Option 1, with this stipulation, has been my approach thus far. |

There's generally a recommended window where the filler can be applied without sanding, but after full cure, it probably should be sanded prior to ANYTHING being applied on top. Option 1, with this stipulation, has been my approach thus far. The DPLF spec sheet says up to 1 week without sanding. That is also the primer I used. I also went with, and vote for, option #1. I had to repair too much metal where paint had failed over body filler and trapped moisture against the steel. I think either option is fine until the paint fails, but am operating with believe that a continuous coat of epoxy next to the metal will provide that last line of defense. |
