What's the alternative?  |
you dont want to use fiberglass resin and matte. that will be much to rigid and will probably crack on that bumper if it even sticks.
My suggestion, and the way i was taught in school, (the right way to do it as far as im concerned). V out the crack on the front and back with a die grinder or some coarse sand paper. Get a role of plastic mesh ( should be able to get it from you local auto paint store) along with some plastic fusor. the brand im familiar with is LORD Fusor 142. Its a 2 part like alot of epoxies but its a plastic repair material for this type of application specifically. you do need a gun for it similar to a caulking gun.
Start with the backside. Apply the fusor generously to the back side of the crack. I say try to make it seep through to the front side so you dont have to re apply the fusor to the front. After you have applied the fusor put a piece of the plastic mesh(big enough to cover the whole crack) on top of the fusor.) you might want to apply some more of the fusor on top of the mesh and spread it around just to make sure you have the crack covered.
Keep in mind this fusor does have a fairly short working time, meaning it will harden fairly quick.
Once the back is all dried up flip it over. If the fusor came through enough on the front side you should be able to sand it smooth and the crack should be gone. if not generously apply more on the front and spread with a squeegie to make sure its covered. You will need to sand it once its tried.
You may want to get another type of fusor to go over the top of the 142 for the front side. I cant remember the number of it but its make by the same company and its red in color. this stuff is like a plastic friendly filler. I recommend it if you dont mind spending the money on this whole process. It comes in a white tube and you dont need a gun for it because it has both materials in the tube and mixes as it comes out.
Ill get off my soap box now. Hope this helps
