Can you look the repaired nature? Not whether it's done hold together.
As increasingly vehivle parts are specious of fiberglass, it is decisive to discern brew repairs in the information. Gouges and holes can be constant at a reason shop, on the other hand repeatedly the fee is excessively high-reaching. The apprehending of repairing automotive fiberglass can seem intimidating, however it is in reality even expanded picnic than most folks envision. The most big-league matters To possess are patience and concern to act.
Instructions
Preparing the Car
1. Sand the world sorrounding the gap to be repaired with a palm sander using coarse sandpaper. You thirst for to sand on ice the colouring layers down to the fiberglass. You distinguish you're there when the achromatic fiberglass layer shows. Conduct it as Rugged as practicable to establish a acceptable bond with the original fiberglass.
2. Decrease a portion of episode metal a infrequent inches larger than the gap whether it is a enormous one. Whether it is a meager hole, you can skip this and go to section 2.
3.14. Allow the fiberglass to cure for a few hours for maximum hardness.15. Sand the fiberglass smooth with the car surface, starting with coarse sandpaper and moving to progressively finer grits.
Drill holes through the car's fiberglass and the sheet metal around the damaged section.
5. Attach the sheet metal to the car with bolts and nuts. The bolt heads should be on the outside, the nuts secured on the underside.
6. Grind the bolt heads flush with the car surface.
Adding the Fiberglass
7. Cut the fiberglass cloth and tear the fiberglass mat into pieces slightly larger than the hole to be repaired.
8. Mix a batch of fiberglass resin with catalyst in a disposable bucket. The exact proportions will be on the resin container.
9. Paint a layer of catalyzed resin onto the sanded area around the hole (and on the sheet metal if it was used).
10. Add a layer of fiberglass to the resin. Begin with cloth if it is a large hole with sheet metal; for a small hole begin with mat. Cloth is more coarse than mat and is good for filling in larger areas, but mat is easier to sand smooth and should always be used for the outer layers.
11. Tap more resin into the fiberglass with a paint brush to completely saturate it. Tapping (as opposed to brushing) removes trapped air bubbles, which greatly weaken the fiberglass.
12. Allow the fiberglass to fully cure (until no longer sticky) if the hole is small with no sheet metal. This first layer will provide a base for remainder of the fiberglass. If it is a large hole, go straight to the next step without letting the resin cure.
13. Add more layers of fiberglass and resin until it is flush with the car surface. Remember to use mat for the outer layers.
Position the sheet metal on the underside of the hole and shape it to fit the contours of the car. This will give the fiberglass something to rest against.4.
As you sand, feather the edges of the repair area in towards the middle.
16. Seal the fresh fiberglass with fiberglass glaze.
17.Paint fiberglass primer over the repair job to ready it for paint. Two to three thin coats are better than one thick coat.
18. Allow the primer to dry and wet sand it with a fine sandpaper to remove any final imperfections.
19. Paint the repaired area to match remainder of the car.
