I'm creeping up on the canopy and within a few months, should be ready to cut and install it. I plan on using SikaFlex, but not sure which would be the best substrate. If I understand correctly, there are a couple of different primers...one for painted/powdercoated surfaces, one for bare metal, no?
I plan to paint the cockpit with a (very expensive) PPG automotive paint, colormatched to Van's powdercoat. It's a two-step process, with primer and then paint.
Everything that will get painted has (so far) been acid-prepped and scrubbed, then alodined. I'll do the same to the canopy frame. But should I go the next step and prime it, prior to bonding? (I'm thinking doing so will make final painting easier, maybe?). Or should I just leave the alodine and bond to alodined aluminum?
(Or don't even Alodine? ???)
After pounding a gazillion rivets, it's time to learn something new...and this definitely *is* LOL! So any help you can provide is much appreciated. I searched around, and read many threads and other builder's logs and photos and such...just trying to clarify things a bit.
TIA!
