N00b-in-training Posted June 22, 2015 Report Share Posted June 22, 2015 I made a quick stop at home today over lunch to slap another coat of lacquer on a couple of small items I built for my wife this past weekend. The normal bowl I use to apply finishes out of was in use with the lacquer thinner I put the brush in this AM, so I grabbed a plastic cup to use for the max of 5 minutes it would take me to apply another coat of lacquer. Well... Turns out lacquer eats through cheap off brand solo cups in about 3 minutes. The bottom of the cup fell out and gave a new definition to flooding the surface, the piece and my finishing table. Thankfully my phone was about 1 foot way and didn't get dumped on. Hopefully I don't have a lot of buffing ahead of me to repair anything the excess might have caused. Lesson learned. Quote Link to comment Share on other sites More sharing options...

Immortan D Posted June 22, 2015 Report Share Posted June 22, 2015 Alas, I've been there too. Dang disposable coffee cups, should have a consumer warning about this! Quote Link to comment Share on other sites More sharing options...
Dave Posted June 22, 2015 Report Share Posted June 22, 2015 I used to work on race cars. Before one of the big races the car was ready to go, on the trailer - I put a little car paint in a solo cup and was touching up the paint to make it look nice. Yep automotive paint will also make the bottom of a solo cup drop. And it only take a few hours to clean paint off the back window, side panels, bumpers....

wdwerker Posted June 22, 2015 Report Share Posted June 22, 2015 Yep. Ya never forget those hard learned lessons ! I use ceramic coffee cups, those things seem to proliferate in my house so the ugliest ones head to the shop. Thinner or paint won't hurt them but they shatter if knocked off the table.

weithman5 Posted June 22, 2015 Report Share Posted June 22, 2015 Fwiw chewing tobacco spittle will eat through a cup on a long drive when it is between your legs. Dave B - race at mid Ohio? I can hear those cars while at my moms farm Quote Link to comment Share on other sites More sharing options...
Trip Posted June 22, 2015 Report Share Posted June 22, 2015 ==>lacquer eats through cheap off brand solo cups in about 3 minutes Been there, done that... You should see what conversion varnish can eat through! I can leave lacquer in my guns for weeks (and I'll admit to the occasional months). Conversion varnish reducer can damage a gun overnight...

Don Z. Posted June 22, 2015 Report Share Posted June 22, 2015 You want real fun? Exothermic reaction of epoxy in a styrofoam cup. You can start a fire that way... Quote Link to comment Share on other sites More sharing options...

Giving apprentices a cup like that for acetone was a apparently a common prank in tool rooms. Quote Link to comment Share on other sites More sharing options...
wtnhighlander Posted June 24, 2015 Report Share Posted June 24, 2015 Oh, no. For acetone, you should use a styrofoam coffee cup, so it pours straight through the bottom! Quote Link to comment Share on other sites More sharing options...
xxdabroxx Posted June 24, 2015 Report Share Posted June 24, 2015 Since we're on the topic, what is everyone's favorite disposable cup for finishes? I've seen the paper cups used a bunch on videos for epoxy, but I worry about the wax for anything that is solvent based. Quote Link to comment Share on other sites More sharing options...
Gilgaron Posted June 24, 2015 Report Share Posted June 24, 2015 Old glass food jars are free and won't dissolve in anything you're going to apply to wood. Quote Link to comment Share on other sites More sharing options...

Dave Posted June 24, 2015 Report Share Posted June 24, 2015 Dave B - race at mid Ohio? I can hear those cars while at my moms farm Yep - I use to work on SCCA GT cars, built a few ITA cars too. I also used to race vintage motocross at Mid Ohio and whatever I could drive to. I found a set of small stainless steel mixing bowls at a garage sale. i have been using them. Whatever finish is left pops off pretty easy after it is dry or a little sand paper gets the thin stuff off. They also came with plastic lids so I can just leave finish in the bowl until I'm done applying the finish. Quote Link to comment Share on other sites More sharing options...
Tom King Posted June 26, 2015 Report Share Posted June 26, 2015 I like these little 3oz. unwaxed cups for mixing small batches of epoxy or poly resin-cheap too: http://aircraftproducts.wicksaircraft.com/viewitems/composite-aircraft-tools-supplies/paper-mixing-cups Quote Link to comment Share on other sites More sharing options...
