Freshly applied and cured body filler tends to clog sandpaper. Here is a trick I have used to save a little time while also prolonging the life of my Long Board or Dual Action (DA) sand paper:
- Once the body filler has cured, take a piece of used coarse-grit sand paper and thoroughly scuff the body filler.
- Next, take a handful of fine, dry filler sanding dust and rub this dust into the freshly sanded filler. If possible, wait a day or so to further dehydrate the filler.
- Then, place a new piece of sand paper on a sanding device of your choice.
- Now you are ready to begin sanding the body filler again.
Utilizing this tip helps to dehydrate the body filler, prevent paper clogging, and saves the amount of sand paper that you will go through.
Another Sanding Tip
- When shaping body filler in a concave area (where the metal curves inward), wrap sandpaper around a rolled-up magazine. This gives added flexibility, yet the length is stiff enough to be able to sand successfully.
Good luck with your body work and sanding projects on your Vintage Mustang!
