Epoxy Laminating Resin 2:1 Kit UV Stable, High Strength for Fiberglass and Carbon Fiber. Boats and Surfboards (.75 Gallon Kit- Medium)

Using this product in restoration on 1971 Sea Ray. This product is super easy to use. Dries extremely hard, and clear and will bond to just about anything. Using this product to bond to wood, old fiberglass, and aluminum. Surface prep and cleanliness are always key to making a great bond. But I swear you could pour this product on a uncleaned and unprepped surface and it will bond just as good. I put some photos on, but the photos really don't do this justice. It dries super glossy and clear and smooth.

I've been working with composites for 30 years, from 'spook" military projects, Kevlar, radar-absorbing material, the works. A lot of what is considered 'stealth' technology, I helped develop 30+ years ago. So I'm very familiar with epoxy resins, how they're supposed to work, what it looks like when they don't- and WHY- and I'm bitterly disappointed with this. WHY?!? I religiously follow mixing ratios, have marked mixing cups to get exactly the right amount of hardener to resin.Too much, and your project will overheat and distort - if not ignite. Too little, and you have a sticky, gluey blob that never cures, and has to be scraped off with a heat gun and paint scraper.After diligently mixing in the exact ratios specified, I got the sticky blobs. If I went from 2:1 ratio to 3:2, I got good results. The manufacturer ratio is WRONG. Highly pissed, now I have a week of rework because of you people.(EDIT) Even when increasing ratio of hardener, some pieces simply would not cure, regardless. This stuff is GARBAGE. I had to tear my car body apart, start all over from scratch. So angry with the time and money wasted, and ruining my existing parts. Find some other manufacturer to buy resin from, because this stuff is absolutely terrible. TERRIBLE.

First time using this brand, parts came out crystal clear and very sturdy. Easy to work with for beginners!
