After some minutes with the Spot Putty dried, sand it using the 600 grit Sandpaper, Clean up with the wet rag again. Using the squeegee apply one very thin layer of Spot Putty to all the surface, as thin the layer is, the fastest it will dry. Now you should have an almost perfect shape of the part. Third body filler layer: Watch for voids and imperfections, apply body filler to it. After the surface is smooth, use the 150 grit Sandpaper and sand it again and you'll notice a smoothest surface. Sand it with the 40 grid Sandpaper and the Rubber Sanding Block. Second body filler layer: Apply body filler giving the necessary rounded shape of the part, and let it dry. Using 40 grid Sandpaper and the Rubber Sanding Block, sand it just to remove the sharp points and edges. First body filler layer: Using the squeegee, apply body filler all over the part to give some body trying to let a smooth finish, let it dry some minutes (time depends on the amount of catalyst) until it is perfectly solid. Material list: Body Filler (with its hardener) Spot Putty Squeegee Wood piece (surface for mixing) 40 grit Sandpaper 150 grit Sandpaper 600 grit Sandpaper Rubber Sanding Block Wet rag Gloves Respirator Protective Eye Glasses Dremel Tool Put your gloves, protective eye glasses and respirator. Mix very well a small portion of the body filler and hardener until you have a one color mix. TIP: Let dry the parts under the sunlight, the heat accelerates the drying process. After the part is solid to the touch, trim the excess of fiber glass mat using the dremel tool. Resin the outside of the part very well and letting it dry 24 hours.

This is really important on the big parts, like the chest, back, legs, helmet etc, because 1 layer stills flexible and weak. After applying the first layer let dry about 15 mins, and continue with the second layer. Repeat this until you have all the part cover it. Start applying one strip of Fiberglass Mat, and resin over it in the inner side of the part. Once the catalyst is added, you will only have 15 minutes to work with it aprox. As long as you work with this you will know how many drops you'll need).

Mix a small portion of the resin (I used 1/4 of a cup) with the catalyst (10 to 20 drops, depending on the weather, if it's hot, with 10 drops it's ok. Put your gloves, protective eye glasses and respirator. Cut the Fiber Glass mat in small or big strips depending on the part size. This will help us to avoid the resin stick to the table.
