covering with ultra cote
I need some help i had a bipe that is covered in ultra cote and i am putting a starburst pattern on it. However i keep getting some small air bubbles between the two layers of film especially over the hollow wing ribs. I used a pin to pop some of them, but i want to do a better covering job. I also don't want to cut out the film underneath in case i want to change it later. Any ideas

Did you spray base covering with Windex then squeegie out liquid
from under top trim sheet? After you let it dry, then you can heat
seal with little or no bubbles. There may be a few small bubbles,
but not the size or number when sealed dry.

Use a firm sponge to force out fluid -- not a dry rock hard one, but
one that is moist but still firm. Wow I'm excited.
It all depends on ambient temp. In the basement it may take 8 hrs. where in the garage it may take only 3 hrs.

You need to use a VERY low heat setting. start at 200 degrees. The glue should not vaporize at that setting then raise too 225-240 after it is down and just touch the edges to seal them

220 degree application
Hey there,
I read something in the Horizon Hobby Quarterly a while back and there were a bunch of tips for covering with Ultracote. One of them was 220 degree application. This is the temperature where the glue will reach the full strength, but there will be no shrinkage of the film, perfect for keeping those straight lines for trim work.
Also, I did not know that you could use the Windex method for Ultracote, or at least I have never heard it used before with this covering. Thanks for enlightening me on how to do that Randy. I'll have to try that on my next project.
