Hi All:

A friend of mine bought several rolls of an iron type of covering,Monocote?, that we can not get the backing off from the finish side. He bought two rolls of green and one roll of aluminum. I have tried to use the aluminum and he the green but we can not get the backing to release from the finish side.

I have tried the two strips of duct tape, razor blade, scraping with a sharp instrument etc .etc. I did get some of the backing to come off but it only came off in very small pieces. We could not get anything but a very patchy piece of covering that was covered with both areas of covering and backing. Both he and I have given up thus the posting. We are not new to this stuff and we have used it for decades with great results.

Has this product been exposed to high temperatures? Is it "stale?" What could be the problem?

Any suggestions? Will silk and dope work over an iron on covering? I am just attempting to cover a hole in the wing!

Tia,

Frank

Clear packing tape. Stick it on as best as you can, then hit it with a heat gun to take out the wrinkles -- it shrinks like 'coat.

And take that "stuff" back to where you bought it and make them take it back!!

I'm hearing more and more horror stories about 'coat -- this is not making me happy, because while I'm kinda thinking it's time to switch over to 'span and dope, I don't want to be forced.

Hi Tim:

Thanks for the reply:

I agree about taking this junk back to the LHS!!!

It upsets me more every day to buy something new and take it home to find that it does not work! It is happening all too often!!!!

Stay wall,

Frank

Hi All:

Other problems that we encountered was this stuff would not shrink of bond when heat was applied! One is left with a loose covering that has a texture of a prune.

I used various amounts of heat and even resorted to using Balsarite but to no avail.

I like the tip about the clear packaging tape!! I have done this in the past on trainers and it was a great fix!

Stay well,

Frank

For the record, I have posted a couple of times regarding UltraKote and I feel your pain!
#1 bad experience: Ran out of blue, so back to the RC hobby shop-it's close-and bought a roll of the exact same color U'cote. This roll had clear backing instead of white, and the wrapper was not a color wrap. It was copied from a black and white copier. regardless of methods I tried, it would not stick. Hobby shop took it back.

#2: 6-7 months later bought 1 roll of gold U'cote, and 1 roll of beige. The gold color came of with the backing, and the beige had no adhesive except in a few small spots. The new owner of the hobby shop said he could compromise with me on a refund. Now I was about to get 2 more rolls at full price and 1/2 refund on the 2 useless rolls I now have.
I haven't heard of this problem but I'm sure I'm not the only instance.
Don't know of any real value to this post other than misery is never happy alone!

There are a lot of different products out there. Some are cheaper than others, some are better than others.

I have no doubt that someone out there has put the packaging from a more expensive product onto a cheaper product to make profit. (yes, this would be "counterfeiting") I am not saying anybody you are interacting with is doing this, but if the packaging does not appear as you expect it I would consider not purchasing it. If you are in doubt then ask if you can open the end of the roll and inspect the corner. If it does not live up to your expectations then walk.

If the shop owner does not stand behind the product he is selling then I would consider taking my business elsewhere.

If the product did not sit in your car in the sun for a couple days (200F happens and ruins coatings) and will not part from the backing then it is defective.

I bought 3 old rolls of covering cheap at a flea market. You guessed it. All were bad. Some of the color came off with the backing. Later I bought 2 more rolls at another flea market. They looked better, but I haven't tried them yet.

Are you sure it was Monokote? What color was the backing?

So far, knock on wood, I've never had the problem of the color coming off the Monokote with the backing. Of course I have had to use something like the tip of the Exacto knife to get the two to start separating. Also I have now noticed that on the newer Monokote I have to use a higher heat range than before. Why can't people leave stuff alone when it is working. I have some rolls that are older than what people say is useful shelf life. I'm not going to mention the covering that gave me the most fits as I will never use it again.

I peel the edge slightly, cut the selvage off the color sheet and let it back onto the backing. This way it comes off easily a little later when I am applying the covering.

I have also had good success using scotch tape on the corner from both sides.

I have used the exacto knife to part the layers many times.

I think the newer film has a bigger separation between glue activation and film shrinking, so it is a little easier to use.

Isn't Monokote printed with the name and color# on the end of the roll? Used to be, in 1/16" capitol letters.
I had some trouble with a batch bought in San Jose in 1983. (the 'trouble' was the backing peeling off color with it, the Monokote was then 20 years old.
