Gel Magic is almost completely non-sagging and makes GREAT fillets... and does so at a GREAT price point!
Measuring it out of the containers is not easy though, and can take time.
It is easy to mix and the color change makes it easy to know when you have mixed completely.
The pot time allows you to get a lot of work done, but...
The cure time is FOUR days. So if you want to keep working on a project, you really need to plan your operations so as to not inadvertently stress uncured joints.
Sometimes glass kit fitment can be wonky. This was absolutely perfect for getting my forward CR on straight, highly recommended this product for wildman glass kits
I used this on my latest rocket and it made installation of the centering rings a breeze!! They are all perfectly square. Super easy to use and very well thought out.
I bought one with a bit of skepticism, figuring I'd give it a try - can't be that special, can it?
I was wrong. They really ARE that special. I now own five of them and wish I'd had them 25 years ago. Super handy tool that just makes things SO much easier!
