How do you fix a Scratch in a fiberglass bathtub?

Elbow grease, and goodies from the marine store (or the auto store, or the hardware store). Good luck!

Fiberglass Scratch Repair

Charley ~ I agree that a good place to start is an auto body supply store or a marine supply store. They both carry just about everything necessary to repair any chip, scratch and even crack in fiberglass, acrylic, cultured marble and solid surface. The catch is that it requires a pretty good working knowledge of the materials that you are working with...... and on. For instance, some fiberglass has a thin, aesthetic veneer that is sometimes paper-thin. If the scratch is the same color all the way through, you are probably ok.

As for materials, you can either use a gel-coat (comes in white or clear.... more of a greyish, reddish transparency) or a product called Akemi (which is really a fine grade of 'bondo' and it is available in white, buff and a yellowish-green transparency. Each product uses a specific hardener. MEKP for the gel and a cream hardener for the Akemi (stone adhesive). Like the other feller said, it depends on how deep the scratch is. If it is deep, say more than 1/32th of an inch, you will probably need to fill it with one of these products, or as mentioned you could use something like fingernail polish, superglue, etc.

If you are talking about relatively fine scratches, then you will probably want to sand the area. If it is on a flat surface, be sure to use a sanding block. In any case, just be sure to sand well beyond the scratch so that you do not have a dip when you are done. Start with whatever grit you need in order to remove the scratch and work your way up to at least 500 grit. Normally, you would use a buffer, wool pad and some compound to polish it back out. If you do not have access to these, you can pick up some light rubbing compound and get somewhat acceptable results. Blending is the key. But like I mentioned earlier, if you see that the exterior color is different than the interior, use the patch method and only lightly sand as need to level the 'patch'. A good course of action is to blue tape right next to the scratch on all sides, use a razor blade to drap the patch while wet, and pull the tape. This will give you much less sanding to do. Hope this helps, it sounds complicated but if you have a good eye, you can pull it off.

Go to a hardware store an get some enamel repair. It's in a small bottle and has an applicator like fingernail polish. Match up the color. Follow instructions on bottle. Surface prep. Apply in thin layers. Letting each layer dry completely. No elbow grease required. Just patients.

Repairing the surface cracks in a fiberglass bath tub is an exercise in futility. The reason is that the fiberglass underneath is weakened and will continue to flex and crack the surface repair. The best thing you can do is replace it with a steel tub. They can be purchased relatively inexpensively at your local home center. It is a bit of a chore replacing them, but not impossible. I have seen lots of fiberglass tubs in mobile homes, and replace them regularly.

DEPENDING HOW DEEP THE SCRATCH IS.....hardware shops sell repair kits.. Corvettes are fiberglass and auto paint shops can help...if it's a minor scratch...rubbing compound and elbow grease. If its a deep scratch go to www.LOEWS.com and search......do not panic its and easy fix.
