Default wrinkle in coating

I just bought the Hangar-9 Alpha .60 and it came with some wrinkles in the coating. I Know this is too be expected but i would like to know how to get them out if i can. i don't have any of the covering tools like an iron or heat gun so if there is an alternative it would be great. I was thinking a clothes iron with a towel wrapped around it but i don't know if it is too hot or whatever so, any suggestions?

a house hold iorn works well on med low, for a buffer a old T-shirt held tightly over the hot plate will do,with light strokes over the area the wrinkle's should tighten up, if a bubble persists then a pin can be used to poke a small hole to let any trapped air out, then they will shrink down.

I've had good luck with a hair drier. Start with low heat and low air. Just make sure to keep the drier moving so not to burn covering.

You must have one powerful hair drier! Most don't get hot enough.

But a clothes iron wrapped in a t-shirt will work if your hair drier doesn't

Try to keep a light touch with the iron until the shrinking is done. Once it is pressed into contact with the wood it doesn't shrink as evenly. Minn is correct that most hair dryers are too cool to do the job.
If you are going to stay with this hobby, and you will, a heat gun should be one of your first tools.

I used a heat gun ( it looks like a hair dryer, but is sold to heat shrink things ... ).

This worked perfectly at the higher settings.

The key is to start on a small area, and once you notice it starting to initially loosen, start making small 2-3" circles.

You MUST get the surrounding regions to shrink evenly as well, so it is a mistake to concentrate only on one small area.

Enlarge the circles as you go working your way accross the component.

Initially the covering will seem to bloom out a bit as it gets warm, this is followed quickly by shrinking... which if you persist too long, is followed by tearing plastic or burning!

Keep the gun constantly moving to prevent damaging any area and to help regulate the temperature of the material.

Once you get the hang of this you can do a plane in just a few minutes.

F-18,
Do what the others above have said to remove your wrinkles. But be ready if you have to do it more than once. Sometimes with ARF's it will take a few times to get all of the wrinkles out of the covering. You may have to go back over it later. A lot of times the covering will loosen up the first time you fly it, so you'll probably have to go back over it again after your maiden flight.

To all. It's an industrial heat gun used to remove vinal in the auto industry. I guess I mis-spoke. I've never actually used a "hair drier", that's just what I call what I use.
I appologize for the any confusion.

Note to beginners:

A commercial heat gun (Often used for paint stripping) can be used, BUT... They get VERY hot and can easily burn a hole in the covering.

So if you use one, be careful!

Many commercial heat guns have variable adjustable temperature settings.

Look for one of these if you are purchasing a new heat gun.

The guns themselves are relatively cheap at Home Depot, etc.

Best answer I can give you:

the blow dryer blows too much air compared with its heat. A heat gun allows you to apply heat in a more controlled manner without all the......uhhhhh.......hot air??????

This is basically the reason the hair dryer is ineffective. Both the heat gun and the hair dryer are typically in the 1000-2000 watt range. And both will reach temperatures above 200C.
