Glen, this will be my second one....lol I really have to think this out, since it's a major operation....lol probably will still use an artist brush, but change the technique for applying the substance. How you may ask, I don't know other than I don't want to make the same mistake that I made before when applying...I am hoping as mentioned that the dry moly lube now acts as a base and somehow the dag will just flow on.....just having a cold one and thinking out loud....

Good morning Glen,
I do not know, I don't see a reason why it shouldn't, unless the two substances are incompatible with each other. Good question, will have to check that out!!! And if not, the moly lube can be removed, no biggie, just more time involved. Thanks for bringing that up!!!

Well been busy with a lot of things lately, working on the 74, getting the new FB page off the ground and just received my next order of dag. So the TB was next in line for work.
I applied the dag a little bit different this time and it worked out just fine. In the drying process now for the next 24 hours. Then I'll have to tap the blades to break them loose. Then will have to work the throttle a number of times to make sure the blades operate freely, then paint and hope to have installed by the weekend.

the dag...

in the next 2 pics, you could see the amount of light that comes through the blades even though the dry moly lube was applied...

half dag applied, half not...

with the dag applied and holding up to the lights....no light coming through...very satisfied with the results....

Still working on the TB, applied numerous coats of the "dag" to achieve the results of no gaps from the secondary blades. The "light test" works really well in checking for would be leaks.....
I also decided not to cut the coolant hose that went up to the plenum, but trim it slightly so I could insert the brass nipple and cap into the hose. Did not want to do the plug and shrink wrap at this time...
So moving right along, need to paint the TB (should be today) and get it all installed in a day or two...

brass nipple and cap.....with Perfect Seal on the threads....

used a 9/16" wrench to insert into the hose....

since I was leaving the coolant hose in place, I wanted to secure it so it wouldn't be bouncing around from engine vibration.....so I attached to a harness and used this piece of hose as an insulator...

hose in the vise with a cutter for a safe easy cut...

nice even cut...

fits perfect....

plastic tied and secured....

Boy that Dag has been challenging to say the least. Once you have undoubtedly mastered the process I bet it would make a great tech article for the Heart of the beast publication.

Thanks for that complement Dave, but I don't know about mastering the process....lol....and it's not the prettiest application....but who sees inside??? lol
I can understand why some don't want to get involved with using it, because it is time consuming (which I have a lot of) and you may need multiple applications (as I did) to make sure there aren't any gaps. And you need sufficient drying and curing time in between. And I am not using the kitchen oven.....that would really stink up the house, so it makes the process that much longer....lol..
Of course the final test is when the TB is back on the car with the engine running. If I am successful with this, then it would be a good article for the HOTB. If not, oh well, onto the next viable solution.....
Will post up current dag pics before installation.....

Also a side note.....after some curing, drying time, before continuing further whether with more applications, or installation of the TB, you need to work the throttle blades multiple times. It will stick shut in either the closed blade drying curing position or the open blade drying curing position after you close it. I use the end of throw away foam paint brush that has the wood handle. Just put pressure on the blade with the bottom of the wood handle, as you are opening the throttle blades. This way there is no real stress on the throttle shaft which could result into a problem....will post up pics....
