Steps to Repair Your Automobile with Fiber glass Cloth

When you are going to repair the car’s body, fiberglass chopped strand mat cloth will be a good choice. It’s easy to handle this. Here are steps:

 

Step 1 - Preparing the Surface

You need to prepare body’s surface before start using the fiber glass cloth. Start by using coarse-grain sandpaper on the entire area on and around the repair. The surface has to be scuffed until it’s smooth to the touch and dull.

Then, take a rag and acetone and clean the area you’ve just sanded. This gets rid of dust as well as oil and grease. If there are any traces of these, the fiber glass will not bond to the surface because it will delaminate.

Step 2 - Cut the Cloth

Using the utility knife, cut one layer of the fiber glass cloth to the size of the area needing to be repaired. You’ll need to cut a number of other layers, each one smaller than the last, until you have enough layers to fill the area being repaired. Stack them to make a mat of fiber glass cloth and put aside for a few minutes.

Step 3 - Mixing the Resin

To mix the resin, pour it into a bucket along with the hardener. Use the proportions indicated on the containers. Put on a pair of latex gloves before working with the resin mix, then stir the mix very thoroughly until you achieve a smooth consistency. Take the felt roller, dip it lightly in the resin mixture and roll it lightly over the repair area to leave a very light coating.

Step 4 - Apply the Cloth

Soak your smallest piece of the fiber glass cloth in the resin mixture until it’s taken on the color of the resin mixture with absolutely no white areas showing. Apply this piece to the damaged area. Take the air roller and roll over the piece of fiber glass cloth until there are no air bubbles.

You need to repeat this procedure with each slightly larger piece of cloth, putting one on top of the last. Roll each one until no air bubbles remain. You’ll finish with the largest piece of fiber glass cloth. Roll over this hard with the air roller. There’s no need to wipe off the excess resin.

Then leave the fiber glass cloth to cure, at least overnight. Wait until it hardens fully and feels cool against your fingers.

Step 5 - Sanding

Start by using a fine-grit sandpaper on the fiber glass cloth repair. Sand lightly then follow up by using a palm sander. You need to keep sanding until the fiber glass area is smooth. It should be level with the area surrounding it, at which point it will be ready to be prepared, primed and painted.
