Fist I would like to thank everyone here for posting the suits they have completed and how they did them. For my TD I used a couple of different methods to get the effect I was looking for. This whole build and weathering took place over three days. I started off with a set of RT-MOD and had the ab modded for a TD.
I used burnt umber and the dawb method for all of the parts.
Following the instructions from the same thread, I first used paper towel to wipe off the excess. This proved to be harder than I thought. I switched to a damp face cloth from the bathroom across from my den and was very impressed at the results.
That was the last of the paint method I used. I did this build while home on leave from Afghanistan. With that being said I brought back 500ml of real desert sand. I boiled it and let it dry on its own.
Next I ground up about half of the sand in a mortor to get the fine dust that coats everything there. This is where boiling the sand helped, it crushed up very easy.
Next using a very high grade spray booth, I coated one part at a time with very tacky hair spary (guys ask your ladies what is the worst stuff out there and use that).
Next in a large trash bag I placed the part and poured the sand over the sprayed areas.
Once I had finished coating the last part, the first was dry and ready to be "cleanedoff". For this I used the same facecloth from the paint step. My wife wasn't too happy about the use of the first one and not willing to ruin a second. Guys don't use whatever is handy in the bathroom.
The last step was to head out to the garage and seal the sand and paint. For this I used a clear coat spry with a matt finish. I did two coats and used a hairdryer inbetween to help with the getting all of the cracks and to speed up the dry time. There was a trooping for MS the next day I wanted to goto. So after all was said and done, this was the result.
Once again, a big thanks to all who have posted and please feel free to make suggestions.
