Is it good to wrap new vehicles?

You may have a damaged power cord or a defective thermostat in the electric wrap. Unplug the cord and inspect it from the plug to the wrap. Look for crushed and broken wires, especially near the plug and at the wrap.

Plug in the wrap and note the rate at which the wrap's indicator light blinks. If the blink rate is regular, the thermostat may be defective.

If the blink rate is irregular, CAREFULLY and gently flex the power cord while watching the indicator light. If bending the cord
changes the blinking rate, you have found the area of damage.

If the problem persists, unplug and discard the wrap. Repairing broken internal wires can expose you to an electric shock or cause a fire when you attempt to put the "repaired" wrap back in service. Your best strategy is to discard the defective wrap and buy a new replacement-- the safety risks are much greater than the price of a new wrap.

No not ever. They account for less than 1% on all vehicles in use. Electric cars will never work, how would you travel when all you can do is follow the few routes that have charging stations available, no that is not practical. Hybrids are the way to go or Hydrogen fuel cell vehicles like the new Toyota.

Welding is best, but when money is tight, go for the cheapest fix. Wraps are fine.

No. The temperature can far exceed what the muffler wrap is designed for and will quickly burn off. I sounds like you may need a new cat. I have seen under certain conditions, a cat get so hot that it actually was glowing red like you put a torch to it. If I were to try anything and I really wouldn't, I would try header wrap because it is designed to withstand temperatures in the range of 1,000 degrees.Your cat is probably rusting out.

I think you should buy plastic bodied 1mm in diameter cable for your store. I have seen many department stores use these kinds of plastic seal in the bag so that people cannot add more stuff to the bag after buying the stuff. http://www.tydenbrooks.com/Products/Indicative-Seals.aspx provides wide range of seals. Check which one is fit for your store bag. I highly recommend cheap plastic ones for temporary use.

Actually you don't have to buy a crazy amount of gift wrap colors. You can stick to two solid colors and then just use ribbons and bows to create a really colorful decorative look.

I got my hanging gift wrap organizer from amazon.

It has lots of small pockets for glue, scissors etc and some bigger pockets for the actual gift wrap, although if you buy more than a couple of rolls of gift wrap, it's best to find a separate place to store it.

Yes and most likely it is a cheap plastic valve. You will need to turn off the water to the heater and drain it completely. Pick up a new Brass valve at your local Lowes or Home Depot and wrap 5 windings of Teflon Tape on the threads of the new valve. When wrapping the tape on, hold the valve so the threads are up and start wrapping the tape Clockwise. If you do it the wrong direction the tape will peel off when threading it in the heater.
