Unlike classic American cars in the 1950s and earlier, modern cars full of plastic. From the door panels and dashboards to the hood, plastic is everywhere. Although this is an affordable option for car manufacturers to build cars, the fact is that plastic lasts as long as metal.
Eventually, these plastic components expire and break and you have to replace them or live with broken parts in your car. In the sixties, the biggest change from metal to plastic changed.
As the metal became more expensive and plastic technology grew, automakers quickly resorted to plastic as the material of the future. It is not only cheaper to produce, the plastic parts are much lighter and weigh a fraction of what your metal counterparts would get.
In the eighties everything was in a plastic car. Marks the hood of almost all cars made in the late 1990s, and you will probably find plastic engine parts.
General Motors even used plastic composite components in the engine. There is not much you can do if the composite engine parts fail, it is usually a reserve.
On the other hand, the internal and cosmetic components can be easily repaired if you take the time to solve it yourself. All you need are some of the products that are available in every NAPA car parts store.
Cleaning the panel with wax and grease remover is the best way to clean the part without damaging the plastic. We had some sun-bleached plastic door panels from a 1974 Dodge Challenger that needed some restoration.
Over time, the sun eats the plastic and eventually begins to peel off just as the steel is oxidized. In addition to the crunchy surface, one corner of each plate was split. These plates are hard to find and expensive. 20 and 3 hours (without curing times).
We use non-fluffy business towels to clean the piece. You should clean the wax and grease remover and then wipe it off with a dry cloth. The process starts with a quick clean up. The plates were cleaned with wax and grease remover.
You can use glass cleaner or even soapy water, just want it to be clean before you start. The corners are an area with a lot of stress, cracks often occur here. Then the crack was located and evaluated.
For this repair, the epoxy is added to the back of the board, making finishing work much easier. The crack was closed and sealed with adhesive tape as an epoxy carrier.
With the tape we close the crack and fix it. JB Weld Quick Weld works very well in metal, fiberglass and plastic. It is measured in the correct proportions with the piston.
The tube simply measures the material, it has to be mixed by hand. Then we mixed the JB Weld Kwik Weld. It does not cost much, just enough to cover the repair. Then the epoxy is pressed into the split in the back.
This reduces the number of revisions on the visible side. The epoxy spread over the crack and pushed it to the junction. Then the gap was tightened and masked again to ensure that it remained closed.
Mercury-welding hardens in 6 minutes and heals completely in 4 to 6 hours. After about 15 minutes we removed the tape and showed the repaired crack. It could remain so, but there is a loss of texture that needs to be addressed.
The plate was sprayed for grinding with a white conductor. This helps us to view all damaged areas. Once the repair is complete, we grind the pellet, grain panel 320. If the thickness exceeds 320, scratches will remain on the final surface.
