Highly likely KSO! I gave it a couple of good shots of MS1000 and once that was cured I painted on some more of the Mr Dissolved Putty for good measure. Overnight cure then hit with sanding sticks and water. Looks much better now 
I also spent some time getting detail painting and more sub assemblies sorted. The chassis and floor pan are mated up now and the engine 90% done.
