I have several questions. First, are the nails galvanized or stainless steel? If they are galvanized, I would prime them first with Ospho before caulking and then prime with a regular primer. Ospho is a green liquid that will turn rust black and prevent bleed through on your paint. Galvanized nails rust fairly quickly and this will head off a problem in a year or so down the road. You can also use Hammerite Rust Cap Primer for the nails. (Many painters tell me that QTips work great for applying Ospho). If they are stainless, I would caulk first and then prime the surface. This will prevent any flashing effect from the Ospho on the finish coat. I would actually prefer to use a spackling compound that will stay somewhat flexible, but you can use caulk also. Is the siding a hardi-panel or hardi-plank? I have not seen any real wood siding pre-primed in my market. If it is hardi-plank, I would prime the siding with a good latex 100% acrylic primer. You could use 123 by Zinsser, Suprime by Pratt and Lambert, or FreshStart by Ben Moore and then topcoat with your choice of paint. Every paint company will manufacture a 100% acrylic primer to use with their topcoat. The primer used on siding as well as steel doors is to protect the product in shipment. It is still intended to be primed before painting. I would highly recommend that your primer be manufactured by the same company as the paint for warranty reasons. Make sure you use a really high quality caulk. I have found that Big Stretch Caulk by Sashco is the easiest to work with of all the caulks on the market. It is paintable. It is a little expensive, but is very flexible and smooths out great. Consider having your primer tinted 1/4 to 1/2 formula of your topcoat color. It makes the paint cover better. The primer will still be a little light to the finish coat so you can see any areas you have missed when applying your topcoat. I do recommend two coats of finish paint.

I kinda figured that pulling the sink would be better. I'm a little worried about the weight too. Not that I can't pick it up but rather setting it back down and making a mess of the caulk job.

It is new to NBC....Its already available on DVD. I'm looking forward to watching it. From a quick google: "Published on Apr 15, 2011 10:36AM 0 Comments Television's best family series, Friday Night Lights (7 p.m., NBC/Ch. 5), returns to broadcast television for its fifth and final season. And the East Dillon Lions are making some noise. Let's just say that they aren't going to go 2-8 again this season. This 13-episode season of "FNL" has already aired on DirecTV, and it's already out on DVD. (That has to be a first for a show on a broadcast network.) If you haven't seen it, however, this is must-see TV. It continues to portray the most realistic family on TV. That doesn't mean they're perfect - Julie (Amy Teegarden) gets herself in waaaay over her head with some really stupid behavior when she goes off to college. And the marriage of Coach Eric Taylor (Kyle Chandler) and Tammy (Connie Britton) looks like real life. Because it's not perfect, either. But they're amazing people who not only clearly love each other but love what they do and the kids they work with. For those of you who haven't seen Season 5 yet, I don't want to give too much away. Except to assure you that, when the final episode airs, it won't leave you hanging. It will give you closure. And it just might make you cry. " Here is a link that might be useful: FNL

What a messy, ugly job. That's junior-grade handyman level work you have there. In my experience, regardless of the material, most tradespeople don't follow the installation instructions to the letter. However, experienced ones read them so they know what they should do, and through that experience they've learned what they can do and still get an acceptable job. It doesn't appear that your installer is one of them. "Certified installer," yeah, right. So he screwed up, and now he's stonewalling you about making the job right. That's money out of his pocket, and he thinks bluster and BS will discourage you enough that you'll give up.. Time to call an attorney. I expect you're going to need one.
