can I use this method if i cracked the bumper of my car?

Yes, you can use the method on the video to repair a car bumper, although the instructions could be more specific if it was known whether the bumper was a thermoplastic or a thermoset composite.

i cant get at the inside of the crack what should i do ?

You will need to grind the front side carefully and fill in with as much reinforcement as possible not to go beyond the finish surface. Proceed with "body work" on front. Gelcoat or paint finish the part.

This video is a winner. Basic but informative.

@celicapunkracer Yes, it's feasible but will be a more extensive repair! I would highly recommend a trained Body Shop person for this! Hold & clamp the bumper to its original shape. Bring the cracked area together like a puzzle before repairing. CLEAN & PREP AREA THOROUGHLY BEFORE ANY RESIN & GLASS WORK. Double (at least) the amount of glass & resin to hold the shape & extend the width of the reinforcement on the back. A steel cross member within the fiberglass is recommended for added strength.

Yes. See previous post.

Yes, you can use the same process on your boat. You will need to consult the boat dealer for a small amount of paint or gelcoat that matches your boat for the " finish" of the repair. Use car body filler to take up the space of the chunk before using the paint or gelcoat. (No repair lasts forever, so be prepared to do it again depending on use of the boat.)

would this technique work on a boat?
