    System 3 Polyurethane Clear

    Ok... Sorry for the delay.... I placed one of my panels in a ziplock bag with 30% heli fuel, let it sit for 48 hours... I took a razor blade and cut a checkerboard pattern into it to allow the fuel to have full access to the paint and primer. The only issue I found after removing it from the fuel bath was that the epoxy primer underneath the water based polyurethane separated in a couple small area from the aluminum panel. The WB Polyurethane is 100% unaffected by the fuel. Aluminum is not the easiest substrate to get good adhesion with, which most likely explains the epoxy primer lifting in the two small spots. Overall I’m quite impressed. Sent from my iPhone using Tapatalk

    System 3 Polyurethane Clear

    I prepped several aluminum test panels and a piece of epoxy resin sealed 1/16” aircraft ply. Two coats of white epoxy primer for the first step. My plan is to take one of these all the way through final top coat and the others will only be coated with each step in the process. So I will end up with a primer only panel, one with primer and the white System 3 waterborne polyurethane, one with the System 3 poly with SEM fluorescent additive tinted clear coat, and one that’s been painted with the System 3 poly and only clear coated. Later on I’ll be soaking these test panels in acetone, lacquer thinner, and high Nitro fuel. The key to getting a paint film to breakdown prematurely, if it even will, is to scratch through it down to the bare substrate allowing the solvents, chemicals, etc to also attack it from underneath. I’m curious to see the results... The other products that will be sprayed on my test panels. This epoxy primer is really awesome stuff, I highly recommend giving it a shot if you’ve never used it before. And it’s about 1/2 the cost of Klass Kote, sands like a dream too. The touch-up gun I’m using. HVLP with a 1.0mm tip. Sent from my iPhone using Tapatalk

    Not for Nitro use, or...? Sent from my iPhone using Tapatalk

    This is including everything going in/on the boat. Minus the final finish of course... Thoughts? Sent from my iPhone using Tapatalk

    Huge shout out to Joe at ZippKits! He hooked me up with one of his prototype 21GT stands and a newly designed glass cowl, which fits like a glove. She’s pretty much ready for paint. That’ll be coming soon. Sent from my iPhone using Tapatalk

    Total Boat Epoxy

    If you watch the video on their site, this resin is very thin. And you can thin it down with solvent even further. It appears to be able to drop off of a paint brush like water. Kind of like Thompson’s Water Seal. I originally posted about this because I’m going to be building my first non-rigger boat, and sealing with a spray gun was my thought. And maybe do touch ups with a small brush. Is automotive clear coat a suitable sealer also? Forgive the obvious, I’m a newbie to boats... Sent from my iPhone using Tapatalk

    Total Boat Epoxy

    Just for sealing/waterproofing inside areas...It’s probably overkill for our application after reading a little more into it. Sent from my iPad using Tapatalk

    Has anyone ever used this epoxy in particular? Total Boat Penetrating Epoxy I’m curious, just looking for some feedback...

    System 3 Polyurethane Clear

    I ended up ordering a quart kit of the bright white. I’m going to epoxy prime a couple of test panels and paint them with the 2k waterborne polyurethane paint. I’ll post an update in a week or so. Sent from my iPhone using Tapatalk
