There is more to epoxy than the price - I looked at the JeffCo (Rhino Liner) TDS and it does not have a lot of information. Tensile strength, peal strength, Tg and others are important for various uses on the RV. Practical things like wet out and application ease are good for a nice finished product. It is hard for me to give a good answer.
But, I can say West has very good technical data and tech support. Easy to layup and has good wet out properties, reasonable Tg.
As an alternative, PTM&W is a California supplier of many resins. They have a full line of offerings and also have excellent support and tech data sheets.
Aeropoxy is one of their lines that is available for our uses. I have used several PTM&W products and the West Systems. No experience with Jeffco, sorry.
Maybe Jeffco has more information and/or you could get some and let us know how it performs in your tests. Testing is fun.
