Clearcoat Recommendation for Oahu

I have used the System three wr-lpu on my last two boards and it is a PITA to work with. I have used brush, roller, and spray. Last time the spray looked pretty cool, but it didn’t cure right.

Was going to try the two part urethanes for car clearcoat and was wondering if anyone had any recommended brand that is available on Oahu?
Most places won’t ship hazordous materials like that so it is easier just to buy locally. I have found a Nason and PPG dealer but am open to any recommendations. Just seems like so many options and not sure what the right brand and formulation is for the 2 part clearcoat.

Thanks ahead of time!
