Fishtex,
What do you use it on? Aircraft Carriers?
I called the local store and he said his clients are industrial vessels so did not know what a small fiberglass boat would need. If it worked out I could save $200 but I don't want to do the painting and sanding twice.
We’re painting UAV’s and it’s usually Polane, and yes they do paint aircraft carriers with SW marine paints. We paint based on what’s called out on the print. You can see the mil specs on each paint, primer or coating. (It’s a two part polyurethane). Navy customers had a different spec but I can’t remember which combo of primer/paint they used, sorry about that.
I can see wanting to use that discount but you need to be able to get the results you are after, cheaper and bad finish is not a good combo. For example, Roll and tip Awlgrip or Sterling is doable by most non pros but if you want to go with Sherwin-Williams, you’ll probably need to spray. I’d just call support or send an email and describe exactly what you’re after and they can recommend, they have helped me in the past and it worked out fine.
Keep in mind, these guys are used to commercial/industrial/Aero-Def customers. A lot of the marine stuff is all about corrosion protection which is not the concern here. They will recommend certain primers for certain substrates but may change based on temps or whether you are brushing/rolling or spraying. They’ll also have reducers they like, etc. I had a guy that used to paint airplanes and he had all kinds of combos he liked, from years of experience.
In any case the Sherwin-Williams stuff is top notch but it’s damn expensive and may not be the easiest to use in some applications.
BTW, System 3 primer gets good reviews from everyone I’ve spoken with. Use quality two part systems and do the job once, it’ll be worth it when it’s time to sell. YMMV. Good luck.
