Some of the best ideas are cheap but will save you loads in the long run. Here are a few you can bank on.
It's In The Bag
A crisp, neat, straight paint line is a delight to the eye and is easy to achieve with careful application of masking tape. Your efforts unfortunately can be marred by paint creeping under the edge of the tape, ruining the effect. This is often caused by minute pieces of dirt sticking to the edge of the tape as it is laid down. Avoid this by storing tape in a resealable zipper storage bag when not in use. The bag will keep dirt off the tape and prevent half-used rolls from drying out between uses.
Zap The Tape
Nothing is more maddening than a roll of masking tape that won't unroll, but only comes off in little bits. Before tossing it in the trash, an ornery roll of tape can often be brought back to life with a quick blitz in the microwave. Don't overcook it: 5 to 10 seconds is often more than enough to revitalize the adhesive and return the roll to taping nirvana.
Keep It Solvent
Boat owners use lots of expensive caulks and compounds in cartridges. Half-used tubes that sit for more than a day or two often dry up, then get thrown in the trash. To avoid wastage, cover the end of the cut nozzle with a good dollop of petroleum jelly. It will keep the air out and prevent the contents of the tube from hardening. Next time you need the caulk, thoroughly wipe off the jelly and squeeze out a little bit of caulk to be sure the inside of the nozzle is clear of jelly.
Cheap Hand Cleaner
Many jobs on the boat can leave your hands filthy. For a fast-and-effective hand cleaner that's good at removing grease and grime, pour a little olive oil on your hands along with a sprinkling of sugar. Wipe with a paper towel, then wash your hands with soap and water.
