Not that I have anything against prostitution, it’s their clientele who are generally the arseholes…

No - it's because they wrote a book to trick people into buying epoxy.

@ PurpleOnion,
I do that work all day and if you were near me in NJ I’d say bring it over and it will be finished in about an hour. I’d personally use it until the end of the season if your not racing, then repair it over the winter after watching a YouTube video or 2.

The Gougeon Brothers have done more to advance the science & art of composite(wood/ply/glass/carbon/epoxy/poly/foam) than any other manufacturer or player in the composites industry. When it's said they wrote the book, it's true. They did it to sell epoxy, but also to share techniques that they invented or perfected that have changed the industry. You may not be aware, but they used to be the world's largest fabricator of wind mill blades until the early 1990's. They do real in house testing of methods of construction. Selling epoxy is one aspect of their company. They have been making a full range of pro epoxies for over 20 years, that is news to most people.
You won't make any friends on here bagging them.

Where I come from we don’t feel obliged to rush out and buy WEST stuff (it’s not always available anyway), I choose from a variety of epoxy manufacturer’s. And will generally attempt to buy from local manufacturers. I have bought some of their stuff and yet somehow still feel clean. The techniques espoused in their book are to be found from a variety of independent authors. They do a reasonable job of promoting epoxy. In the end it’s all about the preparation. I’m sure Purple Onion will be able to sort it out.

Thank you for the offer. I may reach out. I took some of the advice above and found out that I'm closer to an untrained monkey than a trained one. I used Marine-Tex and the leading edge looks good and just requires some sanding. What I did with the bottom may require a little more attention. Unfortunately, work is a little crazy right now and I haven't been able to finish the job. Thanks for all those that provided guidance.
Sanding is key here. Make sure you are only hitting the high spots. You can put your sand paper on a paint stir or hard sanding block until you get your new surface almost even with the old.
An even better way to do it is to apply the marine tex putty with a razer blade so you don't need to sand much at all. It's a lot like trowling on drywall mud on a much smaller scale.

Is it safe to assume you can easily tool green Marine Tex similarly to green epoxy?

I learned from an industry pro years ago that there are only a small handful of base resin producers. All the retailers of epoxy products buy from them and add their proprietary additive packages to tailor the products performance - fast cure, clarity, mix ratios etc. etc.
This means there is no real difference in "quality" only in specific characteristics.
For example, I prefer a 1 to 1 mix called EX88 for ease of handling - it works just as well as WEST for a fraction of the price.
And no farting around with pumps.

I have only dabbled in small projects. But I like the Gougeon Brothers and West System. Their epoxy is premium priced for sure. And if you check the SDS, you will find that it contains benzyl alcohol, which does nothing to improve any physical properties of cured epoxy (but does make the resin thinner). There are other ways to lower the viscosity of the epoxy resin. You can buy lower viscosity epoxy resins now which contain no thinners. Or sometimes you may not need the low-viscosity. Why buy epoxy thinned with benzyl alcohol, then add colloidal silica to thicken it up?

I will defend the Gougeon Brothers. I dislike West System epoxy. Its a high blush, very amber, pain in the ass 5:1 ratio that is the wrong viscosity for almost everything. It would be better if it were thinner for fibreglass, better if its thicker for wood. There are other brands of epoxy I prefer.

Epoxies are the same as paint (and varnish) in that most products from the major suppliers are good; its a matter of picking one that meets your needs and get experience working with it to understand how it behaves.
