Sorry for a asking so many paint questions.
Has anyone sprayed Jet Flex solvent based interior on bare prepped aluminum? I ordered mine and plan to shoot test samples both on scuffed bare aluminum and scuffed P60G2.
I planned to scuff with scotch brite and clean as usual so it should be a good mechanical bond.
After several calls to Sherwin Williams corporate and stores, the consensus is to spray a primer but, they won't agree on which primer. One said the P60G2 would be fine if scuffed. Some recommend Jet Flex primer. Others say I have to use SW epoxy primer over P60G2 and bare aluminum.
Some parts already have P60G2. That's three coatings on those parts. They say P60G2 is not meant as a primer for non ferrous metals or top coats and yet their web page says the contrary and it is compatible with several top coats. Of course it doesn't say which.
Frankly it's annoying to get such mixed information. So I'm hoping for experienced opinion here. I know it's an expensive airplane but every gram counts. I'm not opposed to spraying primer first but I want knowledgeable opinion on what and why. I read others spraying Jet Flex on QB fuse parts so I know it's been done.
So, with respect to Jet Flex Solvent Based...
If you sprayed Jet Flex SB over QB parts, how did you prep? Primer? No primer? What primer? How's it holding up?
If you sprayed Jet Flex SB on bare prepped aluminum? How did it hold up?
If you sprayed Jet Flex SB over a primer on bare aluminum first, what primer? How did it hold up?
