  • Bondo Fiberglass Repair Kit
It is a very well made product when you mix and apply it right. There was a rust hole in the back of my sons vehicle the size of a baseball. We used this bondo and the completed look is not noticeable. I only wish I took before and after pictures to show.

  • Easy to use
While I was at work last year someone dropped something heavy on the fiberglass top of my VW campervan. With little experience and knowledge of fiberglass patching I was able to patch and paint the area so that it’s barely noticeable.

  • Works perfect
I like how hard it gets after drying. Its just as strong as the rest of the body i repaired. I used it with my golf cart.
