Putty and Guide Coat

Where did I leave off?
It's amazing how fast things change on a little boat like this, and yet, when you look at her nothing seems to have changed at all.

I'm in the middle of processing several thousand photos into video from the past two weekends. I fear that when I finish all these videos that the full build will take upwards of an hour to watch....not really a youtube friendly video haha.

I left off with the application of putty to the interior of the boat....

We let that fluffy fairing putty dry and then I brought home some guide coat from work. Guide coat is great stuff. It's typically an automotive product (I think) and comes in several colors. It's basically a very thin spray paint.
What makes it so fantastic is that you spray it on, and then, when you sand it remains in all the low spots and gets sanded off all the high spots so that you know where to add more putty and what need to be sanded down.
You can also draw lines with a pencil or even go with a light misting of real spray paint if you can't get your hands on guide coat.

Also, we only put putty in the cabin where you will be able to see it. We didn't bother sanding under the floor boards (yet) and we aren't too concerned about the area behind bulkhead 2.

For all this putty work we haven't been using the MAS epoxy. T brought home some leftovers of this nasty industrial epoxy that we used on a really big project at work and we used that for all the putty. The stuff smells horrendous and has more safety warnings on it than a toxic waste dump, but it did work pretty well. Its a bit thinner than the MAS and takes much longer to cure completely but thankfully it did the job.
P.S. This epoxy is why our putty turned out so white... The MAS cures a little yellow, but this epoxy cures almost clear/greenish. (in case you were wondering)

You can see the guide coat as dark spots at the top of the putty
