You have seen the end results but I'll back up a bit to show some of effort that went in to achieving the end result.
First the Harpoon was prepped for paint at home. This involved repair, dent removal, crusty screw and Dzus replacement, some body work and lots and lots of cleaning.
Here is Cade, and Ricky in the inside, finishing up the skin repairs that were started by the Colorado Boys a while ago.

Larry was removing dents and using body filler to smooth them out. The skins are pretty good on the Harpoon but there are a few places with road rash that needed his attention. You can see some of the rusty screws on the left that are some of the many in need of replacement. Lots of new screws to go in prior to paint

The old markings on other areas were cleaned off with soda blasting. Here is the gang on one of the work weekends going at the endless cleaning and prep work needed

Scott and Ken working on the belly

Mike and Ron changing hardware on the wings



Ron scrubs the flaps with Scotchbrite. Pretty much the whole airframe was cleaned by hand like this to be sure it was clean and ready for primer

Larry and Jeana having a good time working on the Harpoon

Ken was scrubbing the nose and replacing the old transponder antenna with a new one while Ricky was getting the new intercom up and running

Lots of cleaning and prep. Preparation is 90% of the battle.
While the cleaning and prep was going on the cowlings came off for their own special attention. The old rusty Dzus buttons were replaced with beautiful new ones that I bought about 30 years ago from an old warehouse in Burbank. I have to wonder if they were WWII Lockheed PV surplus as nothing in that old warehouse was newer than 1945. They were the perfect size for the PV-2 cowling. I thought they would come in handy some day.
We hadn't replaced so many Dzus fasteners at one time before (over 500) so with a great idea for a removal tool from Rich Palmer we fabricated our own (since we couldn't find one to fit the portable drill) that worked great for fast production work and fast it was. Here is Jeff and Phillip going hard at removing over 500 old Dzus fastener studs by cutting out the collars with the new magical tool. Thanks for the idea Rich!

Here is a shot of one of the smaller Dzus fasteners to be replaced. Most of the 500+ were FA6 1/2's.

Unfortunately we had very few of the correct length collars in stock but a lot that were about 1/8th of an inch too long so we made a tool to hold them and shortened them up to the correct size. A lot cheaper than buying new ones


After the old Dzus fasteners were removed the cowlings were cleaned with soda blasting and then prepped with acid wash and alodyne. Then they were primed on both sides and the inside was painted dull aluminum. After this we would install the new Dzus fasteners.
It is amazing to me how many comments I received from folks coming by the shop saying I should paint the blue on the outside of the cowling and then install the new Dzus fasteners. They said it would look a lot better with shiny new unpainted hardware nezt to the blue paint. This is great for a custom build but to me it produces what I call the zipper effect and is completely the opposite of the main idea of the paint being camouflage. I also have received grief over the flat paint for the same reasons but that's okay. No zipper effect or gloss paint on this old bird and when asked why I chose to paint it this way the answer is simple. I didn't choose the paint job, the US Navy and Lockheed did it this way and I am simply recreating what this PV-2 carried when she left the factory.
Back to the cowling...
Here are Jeff and Phillip setting the new Dzus studs in the collars in the cowling. Jeez there are a lot of these to do but they turned out great.




Now the cowling has to go back on so we can fly the Harpoon to the hangar where we are going to paint her



It was a late night getting her all cowled up but the gang pulled through and got the job done
Here is the gang posing for a group shot before we were ready to head off to the paint the old gal
Alex, Ricky, Jeana, Phillip, Jeff, Cade, Larry and Mike

Getting all cleaned up to fly her and just get oil all over the place once again...clean, fly, clean, fly...repeat. Welcome to Warbirds
