Primer-Surfacer Applied To Fender:  |
Paint Prep: At this stage of the repair apply medium coats of primer-surfacer to fill the sand scratches left by the 80 grit paper. Don’t apply the coats too heavily because that will trap the solvents and prolong drying time. Apply primer only to sanded areas of the panel where either the paint was feather-edged or where there is body filler. Do not spray primer-surfacer on unsanded paint. It will not adhere properly. |
 |
Tip: Don’t buy spray cans of primer from your local hardware store because plain primer does not contain the heavy solids needed to fill the sand scratches. Obtain the real thing from a professional refinish supply house. |
| Applying Primer-Surfacer: | Use either a siphon feed gun or a gravity feed gun. Use a tip size between 2.0 and 2.4 mm because primer-surfacer contains heavy solids and requires a larger nozzle orifice than the topcoat. Keep applying coats of primer-surfacer until there is enough buildup to sand smooth. Click here for explanation of gravity feed and siphon feed spray guns |

Warning: Be sure to wear proper protection for breathing and handling paint and related chemicals. Use a supplied air respirator and wear disposable gloves. Consult the manufacturer’s recommendations regarding the safe handling of these and other related materials. |
