If you sandblast it to bare (shiny) metal POR (Paint Over Rust) will not adhere without their primer. Powder coating requires bare metal. Powder coating is the way to go if you can get to good metal on a part and the part can be cured at 450 degrees in an oven or by a IR heater. POR is a viable alternative if the part can't be removed from a car and is rusty. I have used POR on floorpans and it works great. One caution, when they tell you to use rubber gloves they mean it as it will not come off your hands (voice of experience). I also powder coat and it is amazing the professional results you can get and how tough it is. Limitation again are the temperature and the size of oven you have available if you are doing it yourself. Eastwood automotive has a good selection of powder coating equipment and materials.

The Gas tank cover on my Delorean has some rust on it and I'm sure more under the old epoxy. I am going to bring it in soon to get it sandblasted and I was thinking; what would be better painting it with POR-15 or bringing it in and having it powder coated? I'm pretty sure that both will give adequete protection but I am not that familiar with powder coating.
