What Is The Acrylic For

1. What is acrylic and why do some people have a coat of it under their cars? Why they need for it? Should I use it, or is it just an accessory?

2. Do I really need to protect the bush with alumunium foil before it hardens? Why don't they do it before it comes out the factory?

3. How do I know if my kancil is having a battery earthing problem?

4. What could be the cause when it is hard to start my Kancil, no matter what time of the day? What makes the car jerk sometimes? Why does the cabin light blink when it is on?

5. Do I need to treat the battery by adding acid or something promoted by the petrol station?

Reply:
1. Almost all paints used for vehicle are acrylic based and the clear coat is used firstly as a protection for the base, or color coat and secondly to give a good shine to the paintwork. This reduces the need for regular polishing as the clear coat holds a shine much longer. Polishing is still needed occasionally as the clear coat becomes contaminated with dirt etc.

2. Covering the bushes with alumunium foil is not going to help much because deterioration of the bushes is caused by constant load, and if it is rubber based, by zone in the atmosphere.

3. If the earthing problem is serious, you will have difficulty cranking the car but normally there are so many earthing points that you would not notice any deterioration in contact. What is important is the earthing strap between the body and the engine as this strap will carry a large current when the engine is cranked and if the contact is bad, it can heat up. Also never remove this strap as the current may try to find its way through throttle cable and start a fire. This may explain your problems in question no.4, and maybe you need to look at the earthing connections, mainly the battery to body and the body to engine.

5. These additives have been around or a long time. And frankly their effectiveness is unreliable. I would not use any of them in a good battery but if the battery is dead, I may try it as a last resort to get it going again, but frankly the battery will not rejuvenate itself.
