Bondo isn't fair-minded for your automobile.
Once you have a layer of Bondo-resin brushed in and hardened, you must back it up with a stronger material such as fiberglass, which naturally bonds to the first layer. Any material can be used, however, from plaster to self-expanding polyurethane foam.
Undercuts
Bondo-resin is extremely concentrated when it sets up. As a denouement, you hold to avoid using it in dense moulds that involve undercuts. An undercut is an environment on the mould that allows the Bondo-resin to seep in, locking the two stable upon hardening. Fill undercuts in rigid molds, such as those mythical of plaster or fiberglass, with modeling clay when using with Bondo.
Undercuts are not a dispute provided you are pouring thinned Bondo into a mould untrue of silicone, latex or another Supple news. All the more provided an undercut is demonstrate, the mould can be peeled off of the laborious Bondo-resin.
Mixing and Catalyzing
Alloy Bondo and fiberglass resin in a disposable paper bucket. Add the Bondo first off, then thin it with resin until it flows conforming maple syrup. Use a paint stick to combine the two materials. Once the mixture is ready, add the catalyst for both components in the correct proportions. It is very important to mix in the proper ratio of catalyst, which is provided on the Bondo and resin containers. If the mixture is over-catalyzed, it will harden faster than it can be used. If it is under-catalyzed, it may never harden at all.
Pouring or Brushing
Pouring a small, solid object with Bondo-resin is relatively simple. Pour the mixture slowly into a mold and allow it to harden. If you are making a larger object, however, you may want to brush in a layer of Bondo-resin to be backed up with another material. Brush in the Bondo with a cheap paint brush. The layer of Bondo-resin should be 1/4 inch thick.
Backing it Up
Bondo is a Trade-mark of Car item filler used every generation in the automotive Production. It is besides used by artists to make objects outside of moulds. Bondo naturally has the consistency of peanut butter, and must be thinned in codification to be poured. This is accomplished by mixing it with fiberglass resin, producing a compound oftentimes called Bondo-resin.
