Has any body used this and is it good, bad, or ugly?
I am currently using it on a Tamiya Spitfire I am building. I used it on the canopy, attaching the canopy parts while I paint the upper surfaces. I am going to remove the canopy parts when I’m done because I will have the canopy open. Unfortunately, I haven’t gotten to the point yet where it is time toi remove them, so I don’t know what the outcome is going to be. fortunately there are two sets of canopies in the Tamiya kit, so if the first is screwed up I can use the second.
I’d just make sure you had a good and thick application of the stuff. I tried it once using one coat which I thought would be enough but it wasn’t. It was a pain in the you-know-where only because it really loused up the canopy of my 1/48 scale B-29. So if you think you have a good amount on it already…add one more coat just to be sure. I’m sure if it’s used properly it will be fine. Learn from my mistake!

That’s an easy-to-do precaution. Thanks.
