I always pull the covering so tight that my knuckles and fingers are sore! This is especially true for monokote.The biggest trick is temp like stang said and make sure you tack the corners. and pull the covering tight before you start actually ironing it down anywhere on the body of the part you are covering.
Are you using Ultracote or Monocote?
If you can post some pics, or pm me, perhaps I can give you some pointers that work for me. Once you understand where to transfer the correct amount and correct heat setting, that stuff lays down like an old...well we won't use that example. LOL....seriously though, it is really great stuff to work with. One thing I can offer up front is this. If you have a wrinkle from a newly covered ARF, chances are that even "IF" you use the correct heat and the correct amount, you could be chasing "that" wrinkle clear across the structure. Simply because it was not sealed down, only at the seams or edges. Not a problem.... This just takes lots of patience and a little bit of coaxing. Once done, it will tighten up and it will look awesome.No i dont have any. I am working on it at my brothers house. Ill take some the next time im there. i am repairing a 40% extra. ill post some pics of what i repaired.
Indeed...been there. LOLI always pull the covering so tight that my knuckles and fingers are sore! This is especially true for monokote.
