Bumper welding

Put a small diameter tip on the nozzle of the hair dryer to obtain a directed jet of hot air.

Heat the parts of the bumper to be welded with a hair dryer, moving the hair dryer for uniform melting of the welded surfaces.

Prepare a thin welding rod from the bumper plastic by cutting it out of a rejected bumper.

Holding the rod at right angles to the crack, fuse beads of plastic on both sides of the crack.

Fuse the plastic of the rod into the crack. Cut the weld seam flush with a cutter. Sand the seam with 150 grit sandpaper without water, then polish with water with 600 grit sandpaper. Apply a coat of special paint for plastics to the bumper.
