Quality proven product! Second time using the gray but I have read that the white seems to be easier to work with. Not sure on that. I’ve been impressed with repairs on fiberglass (one repair below the waterline on cracked exhaust collector) .Worked great!

I've learned about Marine-tex from a boat mechanic years ago and have used it for many different boat repairs. Mix it well and let it cure according to instructions, it's like epoxy on steroids.

It is a great product and I have used the white many times. Purchased the grey and was a bit annoyed that it is really black.

It could be broken down into 4 units of puddy and 4 units of hardener would be best. Hard to sand when dry and harder to sand if to soft. Packs on sandpaper. there is no in between like body putty.

Easy application, but stiff enough to not sag out of filled holes. Much easier than mixing up a batch of thickened epoxy and easier to sand.

How easy it is to work with and how strong it is i have used marine tex for many years going back to when I was young and seeing my father make repairs on boat motors

You can not beat this stuff for filling and bonding. Great for repairs of all types. You can file this down after it cures, just like metal. Sticks to everything!! When you can not solder or weld small pieces this works and holds strongly. I highly recommend!!! :)
