my boss has asked me to tidy up all his outside furniture on his public houses. What will be the best and quickest way off going about this. only going to be doing the table top and the seat top. was thinking quick going over with a belt sander, brush off dust and then paint some all weather varnish on them? any better ideas?. all in all will end up doing about a hundred off them, and all he want is a quick make over?
