| + | "Bondo" is a [http://en.wikipedia.org/wiki/Genericized_trademark genericized trademark] used to refer to plastic body fillers. Plastic body fillers are polyester resins that are mixed with hardeners into a putty. When they set, they become hard, and can be sanded, primed, and painted. | ||
| + | ==Bondo and health== | ||
| + | Bondo was developed as a replacement for lead used as body filler. It's less toxic, although it still poses health risks. Gloves, mask, and adequate ventilation are recommended.

| + | =="Waterproof" body fillers== | ||
| + | Be aware of "generous" marketing claims regarding waterproof body fillers. They are most likely "water-resistant", rather than actually "water-proof". Some people may choose to apply epoxy primer, then body filler, then epoxy primer over the filler. | ||
| + | |||
| + | If using a waterproof paint, a waterproof body filler may be unnecessary anyway. | ||
| + | |||
| + | ==Body filler tips== | ||
| + | In a large flat plastic if or disposable surface Make small batches of well folded body filler, apply small batches in wide thin layers. Sanding and cleaning once partially hardened. This will result in a better finish and smoother transitions. It will also reduce waste; saving money. | ||
| + | *For body lines and peaks on hoods or doors, use a contour gauge to make a custom plastic filler spreader: | ||
| + | #Place the contour gauge on an undamaged area to get the contour. | ||
| + | #Trace the contour onto a plastic body filler spreader. | ||
| + | #Trim out the shape on the spreader. | ||
| + | *Cut filler spreaders to the desired size. | ||
| + | *To clean body filler spreaders, use 1/4 of a 3M scuff pad with lacquer thinner on it. A metal quart can with a lid makes a safe way to store the scuff pad along with some lacquer thinner. | ||
| + | *For reproducing small parts such as gaskets, use plastic body filler to make a mold: | ||
| + | #If the part doesn't already exist, a replica has to be made in its shape (for example, carve it out of soft plastic). | ||
| + | #Apply some wax to the part (this will act as a mold release), and lay it down on a piece of wax paper. | ||
| + | #Mix up some body filler, and place it in a small cup or bowl (the cap on a plastic jug may work). | ||
| + | #While the filler is still wet, place it over the part. | ||
| + | #When the filler hardens, it can be removed and used as a mold. | ||
| + | *When applying body filler upside down, apply the filler to a sheet of thin plastic (such as the side of a milk jug) and press it into place. When the filler hardens, peel the plastic away. | ||
| + | *Use an aluminum ruler to find high and low spots such as doors, hood to fender, trunk lid to fender, etc. | ||
| + | *If using filler with hatonite you can sand filler while still tacky. This will shred the filler smooth easily with hardly any pressure. When finished, follow up with a polyester glaze or add filler thinner to your final coat of filler. | ||
