Jeff Posted December 9, 2002 Share Posted December 9, 2002 Copy the link and paste it into your address bar and you will be able to see it. The beauty of fiberglass is that even as bad as it looks it is still repairable. Lay up a layer of mat on the back side first then repair the crack.

Guest Anonymous Posted December 9, 2002 Share Posted December 9, 2002 I agree with jeff, however I would rough up the back side of the crack and use cloth rather than mat. Then on the top side grind away all of the busted and cracked glass and then mat. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted December 10, 2002 Share Posted December 10, 2002 Easy fix.......complicated instructions: Take it off car. Grind the crack wider by at least 1/2 inch with a grinder ( small air hand held with abrasive disc is best).Rough up the inside of the bumper at least 4 inches along each side of the crack. On the outside of the bumper outline the new ground out crack/groove with 2 inch masking tape. Obtain a 6 inch wide or less roll of roof (electro galvanized) sheathing and sheet rock screws from Home Depot.The sheathing will act as a dam and temporary mold for the fiberglass repair on top of or exterior of bumper.Attach the sheathing on top outside of the fiberglass bumper with the dry wall screw. Use hand ripped and torn fiberglass mat and place "small" amounts upon the 1/2 inch groove and surrounding area from the "inside" of the bumper against the backside of the roof sheathing. Wet the small amount of shreaded fiberglass with fiberglass resin by dabbing with a small cheap bristle brush. Add more mat and keep wetting with resin. Keep increasing the amount of shreaded fiberglass mat and wetting until groove is filled and at least 2-3 inches is covered with fiberglass along each side of groove.You can also lay a strip of fiber glass cloth over the wetted mat for added strength (?) after the shreaded mat is applied and fully wetted with resin. Let fully cure. Remove the sheathing and masking tape from the top of the bumper which should leave you with a fairly smooth exterior surface that can be easily prepped and primed to cover the smooth flat fiberglass filled 1/2 inch groove of the forner crack.. It will cost about $40.00 to get all the materials and about 3 hours to repair. Quote Link to comment Share on other sites More sharing options...
