Supposedly, the hardest decision is deciding what plane type you want to purchase. So am told. I guess they haven’t spent much time in this section yet. If your head hasn’t exploded after reading all it, then congrats, nothing else will do it.
I’ve read from the beginning on all the primer stuff. I’m leaning towards an epoxy primer which many seem to think gives it one of the best seals for the inside, even though I know it's a heavier primer.
When you chose to prime, did you prime all of your inside, alcad sheets and all? And if so, do you have a rough ball park figure of how much weight this added whether it be epoxy primer or other primer? And for those that didn’t prime the alcad sheets but all other metal parts and faying surfaces, do you have a rough estimate on your primer weight gains? I'm plenty inland enough away from sea water, and haven't ruled out just doing the latter, but if the weight gain isn't too bad for doing all of the inside, I'll probably do just that.
In the RV-4 preview plans it describes one example of a paint job which didn’t consist of any primer for the outside, but took other necessary steps for the paint to lie down properly, and also used the minimum amount of paint to still achieve a gloss like finish with Dupont Imron Polyurethane that only added 15 lbs for the entire plane.
If I can get by on 35 lbs or less for the inside and outside of my plane for everything, I think I’ve been worrying too much about it. If the job is done right, about what can I expect on weight gains?
