He all, new guy here just looking for some opinions and maybe a little guidance.
I'm currently in Spain and my RV-7A empennage just arrived. I've decided I want to potentially prime the insides of my plane, at least partially. The problem is that most of the products mentioned here are not available. Self-etching primer, prekote, alumiprep, etc, etc. None of these are available here. I've also decided against the epoxy primers due to several factors (weight, complicated setup & clean-up for my space, others), so this leaves me with rattle cans, at least for the initial small parts.
I have found a couple of wash, basic, and "anti rust" primers in the local hardware store.
Do any of these seem close to the accepted methods available in the US? I do have an APO address here, but it seems just about all of the products mentioned on this forum are "hazardous" and can't be shipped overseas. I found a self-etching primer on amazon.es and almost jumped out of my seat, until I saw that it was almost $50 just to ship a ~$10 can... My wife would DEFINITELY not be happy with that.
So after lots of searching, it seems my only option might be another method? Is mechanical etching (scuffing) enough to get these primers to adhere well? I think I saw someone mention vinegar??
Any help, suggestions, or opinions are appreciated. Thanks!
