Model Railroading > ST SD45 Undec Exploded view

In case you haven't seen one. Received this from the Loder SP in Oregon Cave. 
Edit, checkout Brian Banna build on four undec SD45'S on YouTube.  Very informative. Just found them.

Wow impressive!  Have fun with it!

I got one of those too. It's waiting for me to "update" it to an SD40-3 rebuild.

This is the CNW version.  It should be a fun build!

Looks like a fair amount of weight to these units. Are they using the lower profile tunnel motor drives?

Dave,

The plastic finish on the carbody sides, top and cab is very smooth. Do you think modelers will need to do any preparation to insure the paint will adhere? OK to go with acrylics or tru color maybe Scale Coat I or II?

Thanks.

Alan

You guys are better men than I.

Alan,
The best prep for that would be to do a moderate blast with Aluminum Oxide in a blast booth. BUT, most don't have that luxury. I would say it would be fine with just scalecoat 2 without blasting at all as that is what I'm familiar with and have used on such surfaces. I personally like SC II for plastic, bur SC I is better on metal surfaces such as brass. SC I could possibly etch plastic. 
Hope this helps

Thanks, Dave.

I have a blaster to use. It is in my cool basement on these mid 90s days.

I just clean the model with Poly S Plastic Prep with removes the skin oils and such.
Have had no problems with paint adheision after using it.

Sort your parts, Gents. 

Missing 2 steps out of mine.  Not surprised.   Every undec I have ever gotten has been missing something.   Hopefully these dont take 6 months of excuses to get like Rapido. 

I do wish they came with even a basic exploded diagram.
