+4 for Frank at Performace Props
I'd recommend Frank at Performance Props if you want to outsource the activity.
Unrelated to Frank, I shipped my beloved Warnke prop and FedEx dropped it hard on the tip despite the robust packaging and damaged it. Lesson learned is that there is risk in shipping!
If you'd like to do it yourself I'd recommend this economical 10 step method:
1. Sand away the existing finish and inspect for damage. Fill dings with epoxy or epoxy/flox mixture.
2. Use a three inch foam roller from Lowes and roll on a coat for epoxy primer such as PPG K36 or equivalent. Do not use a lacquer based primer! Sand smooth and recoat as necessary.
3. Don't Laugh!
- Rattle can spray with Rustoleum Professional High Performance Enamel Spray from Lowe's or Home Depot on the top shelf in the paint section.
Rustoleum Link I use the Dark Machine Gray #7587838 color.
4. Spray the Gloss Black #7579838 on the rear of the blades. If you spray it right you don't have to tape the front of the blades.
5. Only spray enough to do the job, if you put it on too thick it will wrinkle at the tips due to centrifugal force.
6. Cure it with some heat, in the summer put it in the attic for a week. In the winter build a foam box and find a way to get some heat into it without burning the house down.
7. Wet sand it with 600, 1000, 1500, 2000 paper front and rear
8. Use one of those Harbor Freight three inch foam polishers and polish the front only with a machine compound from the auto store.
9. Wax the front and rear.
10. Check balance along the way and add material to the light blade. Further balancing is outside the scope of this discussion.
I just hate getting the Devilbiss spay gun out for this activity and all the associated clean up necessary when using the automotive products. I have tried various rattle can products over the last 15 years on my wood blades (three props) and I can say that the Rustoleum Professional has held up the best. In service I consider it on par with the automotive finishes and in some areas superior. My results are posted here:
