Hi,

We have some rotted and cracked exterior wood that needs
filling before re-staining the house. I had been using Mr. Mack's
Wood Fix for this but it is no longer made. Minwax wood
filler is OK for some filling but not all. Mr. Mack's could be
thinned to a near paint-like fluidity that would easily go into
small cracks and leave a protective coating on the wood.
Can you recommend another filler for that also does this?

Thanks,
Gary
