The Monokote will only shrink a little but not much. The ultracote is wonderful at shrinking and stays stuck as well too, and is much easire to iron down. I have use some Monokote recently becaue I order form Tower, but I think I am switching bacck to Ultracote as it is much better.
The Monocote I have will shrink a lot more then the Ultracote I have, until a hole apprears

I use both Monocote and Ultracote and they both have there good points... I still prefer Monocote... They have IMHO the best/prettyiest selection of colors... It sticks down better (at least has), shrinks more etc... I have covered with Ultracote and have it on a few ARF's I have purchased... It applys easier (curves etc) but does not shrink like Monocote.. I have never been able to get the seams to stay down on the ARFS or my onw cover jobs... Ultracote does not have the color selection Monocote has... All depends on what your current project requires I guess..
