GUNNY, Thanks for your post. I called a company that does the metal spray. They do not recommend using the metal spray technique for roller or needle bearings. Th point pressure created by the needle bearings cause the sprayed on metal to delaminate. I appreciate your feddback.

Frank, Thanks for your reply. I too am concerned with lubrication to the bronze bushing......I called Surplus City Jeep parts two weeks back. They did not have any in stock, but said that he would get back to me when they got on ein from a supplier. So far I have not heard back from them. I...

Hi guys. I am doing a complete nuts and bolts restoration of an early 1951 M37. You can check out my progress at www.m37rebuild.com. I have run in to a problem with the transfer case rebuild I can use some advise on. Upon stripping the xfer case I discovere that the input shaft from the...

For anyone still interested in the original goal of this thread, to test how to eliminate or reduce the occurrence of flash rust after a part has been blasted, today I blasted the rest of the test panels and applied phosphoric acid, Metal Ready, PickleX 20 and Hold Tight 102 to the panels. The...

I am in Austin Texas. The humidity in my shop has been averaging around 50% over the past couple of months. Not too humid, but enough to get spot rust on cleanly blasted items after a couple of weeks. I had my front and back axles professionally (whatever that means) blasted about a month ago...

Here is a close up picture of Panel 1 after the test. You can see the scribed lines are clean with only very small pieces being removed from some of the scribed line intersections. Each line is 1.5mm or 0.047" apart. (I do seem to be beating this dead hose myself now...LOL.......)

68427vette Man oh man you are missing the point completely. You are concerned about the look of the panels when I stated that was not the object of this exercise and that I knew that it would not look good. Do you think I am going to use a sponge roller to paint my M37? I think not...

68427vette The MasterSeries MCU ( http://www.masterseriescoatings.com )I used is designed to be applied with a sponge roller, so long as at least two coats are applied a minimum of 3 1/2 half hours apart. I followed the manufacturers instructions to the letter. I know applying the Tm9 urethane...

68427vette, The test panels were not sprayed, I applied the MasterSeries Silver (which is a moisture cured urethane) with a sponge roller, and the TM9 was also applied with a roller. I knew it would leave a "less than perfect" finish, but in this test I was not concerned with looks, rather with...

68427vette, Thanks for your reply, and yes you are right, I am thinking WAY too hard on this. This is my first restoration project though, and I am not in the auto or restoration business so I have no past experience to draw on. There is also so much conflicting information and advice out there...

What's next? Next I will test whether using Metal Ready, PickleX 20 or plain phosphoric acid and resulting flash rust has any negative impact on the paint adhesion. These tests will be conducted over the next couple of weeks. Hopefully this helps someone out there. I know I feel better that my...

Panel 2 and three tests. To refresh - panel 2 was sand blasted, then rinsed with clean water and blow dried with compressed air. This panel did develop a slight flash rust bloom from the water rinse. Panel 3 was sand blasted, then rinsed with the Hold Tight 102 solution and then dried with...

Sanity check! Since the Panel 1 test showed no paint adhesion loss, I wanted to make sure that the test was valid in that it would in fact remove paint from a marginally prepared surface. As a sanity check I performed the exact same test on a red trailer I built a couple of years ago. I know...

Panel 1 test: Per ASTM D3359 I cut thru the paint to the base metal in a crosshatch pattern using the scraping tool. I then applied the tape and performed the test. The shots below show the following: 1 Panel 1 after the crosshatch created 2 Panel 1 with the tape applied 3 Panel 1 again after...

Hi guys, Some paint adhesion test results. After blasting and cleaning panels 1, 2 and 3, I painted them all with MasterSeries Silver primer and then TM9Ordnance polyurethane. After the paint had dried I performed the paint adhesion tests per ASTM D3359 specifications using certified adhesion...
