Car Repaint Project: Day 3 – First layer of paint

It must’ve taken up a good half of Saturday for this.  After taping and spraying the car with primer, and waiting for it to dry, I’ve applied the first layer of paint.  I had no previous experience of painting using form brushes, so I was little frustrated with how things looked and I even had some places where I accidentally squeeze the form causing bubbles to appear and then even vertical drips.  I’ve learned quite a bit on this first layer.

Car Repaint Project: Day 1 – Sanding

Without much time or money on hand, I’ve decided to repaint my 2002 Nissan. It had a Molten Silver color for its exterior according to the spec doc, but the outer paint started to peel off about 10 years ago. The paint looked fine when I moved to New Mexico nearly 7 years ago though, but, now, the peeling paint has made the car look rather shabby to others. I’m not emotionally attached to the appearance of the car I drive, so it didn’t bother me that much.  In fact, I somewhat enjoy wearing and using things that has a look of being well-worn. I think my own pastor and I share a form of camaraderie for having the shabbiest looking cars at the church.  Anyway, my bumper decided to give recently, and when I bought a replacement it came in its raw, black color, and it needed to be painted. I felt that I might as well repaint the whole car while at it.

I heard from a coworker once that an excellent paint job may cost over a 1,000 bucks, and an average paint job typically costs around 300 to 500. I can’t afford that kind of money at the moment, and there are other expenses that are just waiting to move out of my checking account, so I googled the Internet to find a more frugal way and most of the recent answers seem to be around the use of Rust-Oleum enamel paint.  There are actually many guides and write-ups and I’m indebted to them all, especially Styluss, Craig Fitzgerald, and jtech87. I guess this may seem like yet-another-attempt at a write-up, but this is more as a logging purpose for me to keep track of my progress.  I can only allot 1 or less hour a day to this project, and usually it’s in evening.  I may be able to find little more time on the weekends.

Materials (matches Styluss’ preparation, but mine ended up being about 90 dollars total):

  • Rustoleum high gloss white paint – 1 gallon
  • Odorless mineral spirits – 1 gallon
  • Primer spray paint
  • 4″ High density foam brushes – x9
  • 2″ High density foam brushes – x8
  • Paint trays – x3
  • Sandpaper – 2 packs (400 & 800 grit)
  • Painter’s tape – 1 roll
  • Rustoleum clear coat
  • (optional) Car polish
  • (optional, but recommended) Paint mask, ear plugs or earphones, and goggle

The first draft of my plan (similar to jtech87’s) looks like this:

Subroutine M: Wet a rag with paint thinner (100% mineral spirit) and rub down.
Subroutine T:  Use tack cloth to wipe the surface.
Subroutine P: Paint surface.
Subroutine S(n): [Wet]sand with n grit paper.
Subroutine W(n): Wait at least n hours.

  1. Wear a paint mask, ear plugs (or earphones if you prefer), and a goggle if you don’t want paint particles entering your system in any significant amounts.
  2. Clean the car and do S(400), M, and T. Dust off
  3. Spray primer. W(6).
  4. Prepare paint solution (50% Rust-Oleum Glossy White / 50% thinner) and mix it well.
  5. Do P, and W(6).
  6. Do S(400) to get rid of at least 50% of the orange peel.
  7. Do M, T, P, and W(6).
  8. Repeat steps 6 and 7, and then jump to 9.
  9. Do S(800). Get at least 80% of the orange peel, but do not sand too deep.
  10. Prepare a slightly thicker paint solution (less thinner than last time). Use a new brush.
  11. Do M, T, P.
  12. Apply clear coat.
  13. Apply 2nd clear coat (assuming you’re rotating around the car, you can start at the beginning point on step 12).
  14. Do S(800 or higher).
  15. (optional) Apply polish.

I estimate about a week, but with only an hour a day, it may turn out to be longer. Anyway, here I go.

With some preparation time, I ended up with only about 30 minutes of time. In a scale of 1 to 10, where 10 is a thorough job of sanding, I’d probably give myself 5 on this one.  I managed to cover most of the car except for 3 doors.  I imagine I may be sanding for a whole week before I put anything on.

As you can see in the photo, there’s still much more sanding to do.  (Yawn) I need to sleep.

Copying MySQL databases on the same server

Last tested on Ubuntu 16.04.01 LTS (xenial) with MySQL Ver 14.14 Distrib 5.7.13

We had to make a copy of existing databases for development app instances.  For example, a database called xp_main was for the production and xpdev_main would be for development. This depends on how date strings were created, but if you have a lot of dates in the records you may want to turn off the NO_ZERO_DATE mode.  If you don’t turn it off, the copying process can be interrupted. Go into your MySQL console.

mysql> select @@sql_mode;
+-------------------------------------------------------------------------------------------------------------------------------------------+
| @@sql_mode |
+-------------------------------------------------------------------------------------------------------------------------------------------+
| ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION |
+-------------------------------------------------------------------------------------------------------------------------------------------+

As you can see NO_ZERO_DATE exists.  Copy paste the entire string w/o NO_ZERO_DATE.

mysql> set global sql_mode='ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> exit
Bye

Next, we will copy the database using mysqldbcopy utility.  You may need to install mysql-utilities package if you don’t have it available.

$ mysqldbcopy --drop-first --source=root:mypassword@localhost --destination=root:mypassword@localhost xp_main:xpdev_main

That should do it!
