As with all products, there are folks who are Pro, and others who are Con. That was never really my issue.
Mine was one of frustration with a product that did not behave like it did years ago. I used to use a lot of MK and got
a lot of rave reviews of my covering jobs by other club members. After being out of the hobby for a number of years, my
return to it was wth ARF's, and no building, and only patching with covering. When doing what I thought was going to be an EZ
recover job, I found the new MK hard to deal with compared to past jobs.Again, the purpose of the thread, to investigate
if there has been a change. From all the posts, there have been a few who are "in the know" who have posted that
there indeed have been some changes. IMO not to the better, and that opinion has been shared by many here.

That being said, it seems others are doing well with MK, others are not. I appreciate the pics posted by David George,
it looks like you are having good results. One of the big problems I have with using new MK, is the great effort needed
to get it to stretch around edges, and the hard pulling required. The older stuff didn't act quite that way. It was easier to
get it to pull, or "mould" over curves, etc. Another issue is getting it taught and smooth over a open structure in the evening, and waking
up to extreme wrinkles. Yes, most of it can be worked out, sometimes not. But why should wepay good money for a product
that makes for double or triple work. I used to do a covering job once, get it all tight, and good looking, and it would stay
that way for quite a long time. Now I cannot even get it off the bench before have to "tweak it"

Again, the issue is, was it changed. The answer has been "yes it has" over and over. What I have left I guess can be used
as trim. Using trim solvent it seems to stick very well, and smooth. Other than that, to me it is too difficult to work with now.
One issue that makes it very hard with the new stuff. I had an injury to my hand, and my ability to pull is limited. I could work
with the old easily. This is why the new shows to me that it is a different animal.

Of course, these are my results, and my opinions, if you like the stuff, then that is great.
