Re: My first boat restoration, I need some guidance - PLEASE HELP!
Yes, sorry, you got the idea @ the 2X6's. It'll get you 7" off the lot, give you a 5.5" face to lay down on the lot, & a 1.5" edge for the boat to sit on.
I'd use LINT-free clothes. They can probably be found at a big box paint store (HD/Lowes). And when you're cleaning, for paint or resin work, avoid the tack cloths sold in the paint department, in hot & humid locales, they can leave small spots of wax behind & mess up your work. To reduce acetone consumption, you can wash & dry the boat 1st, then most of the sanding debris will have been removed.
You need to be very careful working in an environment that will be tough to control. Acetone is very volatile and letting it sit out on an asphalt parking lot can be unsafe, same with the cloths you're using to wipe down the boat. Spontaneous combustion... Plus people coming outside to smoke. Find somewhere w/ good air flow & out of the sun to lay your rags out, and let the acetone fully evaporate, it will happen fairly quickly.
And the management of the complex may frown on you running those rags through the complex washers & dryers. There maybe some odor involved. Unless they are unusually filthy, they should wash out ok, but you probably won't want to use them for anything else. Don't mix them w/ anything that will put lint on your lint-free rags.
