 Posted: Thu Mar 11, 2010 8:40 pm Post subject: How much primer do I need to buy? |
 |
|
This weekend I plan on driving up to the closest store which carries P60G2, and they are quite a distance away from where I live. So I want to know how much I should buy, so I don't have to repeat the trip.
So, two questions:
a) how much primer have others used to prime the interior of their plane as they assembled it? More than 1 gallon? More than 5?
b) if I try to stock up on enough primer to finish the plane -- how long does paint typically last before it goes bad? Is this a foolish strategy if I expect it will take me several years to finish?
Thanks!
Chris

Primer war.. oh boy. The good news is you decided to prime, there is more than just the interior, personally if given the choice I would do everything outside of the interior, specifically, the tailcone the inside of the wings, rudder, tail HS, etc.. so that means the bulk of the things you'll be doing are at the beginning and half way mark so unless it takes you a while,in my case a little over 2 years to complete all the kits and start the finish kit, which hasn't taken much, if any primer. I have 1/4 left of the 2nd gallon. So in my case, single coat complete parts mentioned above I used less than 2 gallons.
A word of caution, be sure the primer wont cause more harm than none at all, I did it because I live on the coast and thought the salt air might be an issue and my work skills caused a whole bunch of scratches so it was an extra step, but in order for primer to grip you need to rough up the aluminum, which already has a protective layer.
Call the Paint store and ask what the shelf life is for the primer, I think it was 1 year for the wash primer. My house paint primer has lasted 10 years without an issue when I repaint and do touch ups. Another option is go to the website and pull the MSDS, or product description it will tell you the life once it has been opened.
Best of success with the build.

Note how I carefully didn't ask "what primer?" or "should I use primer?". I just am asking about amounts others have used. 
I have my first pieces ready to rivet in my vertical stabilizer, and so wanted to figure out what I was going to do before riveting them together. (So, by "interior" I meant "things which are not the exterior". Apparently I used the wrong word. Oops.) Sounds like 2 gallons will do me -- which is good, since the stuff is expensive!
Thanks so much for your help!

As Pascal mentioned there are many factors in deciding whether to
prime or not, which primer assuming you do, and how much to prime.
Since I live in the desert of AZ, I took a middle road. I want to
avoid potential for galvanic corrosion, while having few worries about
salt laden humidity of the coasts. I only sprayed the areas where
metal joins together..the rivet lines....except for the bottom of tail
cone which got full coverage. Because I bought a QB kit, which these
days appears to have full primer application, my volume needs were not
great, so I went with the ease of self etching rattle cans. I think I
might have used 10 by now, and won't need much more.
So consider whether you are doing the slow build or quick build in
your quantity decision.

Now that I've been to the store I have learned more.
P60G2 is now a "non-compliant" product in California. This means that stores can sell what they have in stock, but not get more. (Apparently they just tightened the constraints on VOC content in paint, and this stuff has too much for the new regulation.) I purchased 2 of the 3 gallons they had in the Hayward store. (Although the guy on the phone earlier this week said they also had 5 gallon cans, the person I talked to this weekend only told me about the 1 gallon cans.) Shelf life of unopened P60G2 is 3 years.
If you sign up for a normal Sherwin Williams account, you don't get a discount on this paint. If you sign up for an industrial account they will give you about 15-20% off. This makes a big difference when the primer is $75/gallon and reducer is $43/gallon.
