Progress from this morning follows. I wanted to plug the spare holes in the mobo tray, since I was going to be painting it. Thanks to Jonni Nitro for the hints on how he did it in his Black Pearl.



The setup ... note, making progress here, as I was walking outside when my husband said "just use the kitchen counter." Not ideal for photos, but I wasn't going to turn him down when he was being helpful.








The tray cleaned of fingerprints and smudge - lots of scratches but those will be (hopefully) covered up in the painting process.






Taped the back of the board, as suggested by Jonni Nitro:






Bondo applied ... oh @#%!@#!!! ... they say you have three minutes to work with it. I tried to fill all the holes with one batch. Dang, should have just done some, then mixed another batch. Not like I need that whole can for this tray. I see a re-do coming...





A close-up. You can see where the bondo was getting dry and didn't want to spread. Not sure it filled the holes.






I brought out "Bondi the Bondo" bear for luck with the next step. Sanded off the excess bondo ... used 80 Grit, then 150, then 220. Tried not to sand too hard. A tad concerned about the mess I made with sanding on the tray, but let's hope the primer covers my incompetence.







Closer look at the filled in holes:






And, a view of the holes from the back - no sanding or clean-up required.






I know this is old hat to many of you, but I've never done this stuff. In fact, I was quite nervous before trying it Next step is a good clean-up, a light coating of self-etching primer, then some regular primer and wet-sanding, then some paint !!! (I'll spare you the step by step photos of the next few steps).
