Re: Resin Cleanup
Use acetone. Brushes and rollers are also disposale. Acetone is quite expensive and it is not worth trying to clean a $1 brush so you just throw them away, you will use more acetone trying to clean it than the brush is worth. Your grooved roller for rolling out the air bubbles is not disposable, just keep it in a small can with acetone in it.
As far as cleaning it from lexan, I would be afraid to use acetone in case it damages the surface. Don't know that else you could try. Sorry.
Uncured resin can be removed with Acetone, not too expensive at AU$3.00 per litre. Also note, used or contaminated Acetone can be recycled by placing it in a container (Glass is good) with an air tight lid, stand it for a day or two and the rubbish drops to the bottom, you can then recover the clean part for reuse.
When cleaning brushes, always dry them with a clean rag as soon you take them out, or leave them in the Acetone inside a container with an air tight lid, this stuff evaporates faster than petrol.
Acetone is a hazardous chemical and you should wear a suitable carbon mask and a well ventilated area.
Application rollers with the usual 10 to 12mm nap need not be special resin roller, I use standard paint rollers, but buy the long ones and cut them down to fit an 80mm roller frame, very cheap so throw away after use and clean the frame with Acetone.
Cured resin can be removed from grooved rollers and other metal tools by heating with a blowtorch, gas flame or even a good heat gun.
A drip of resin that cures on a surface can sometimes be removed with a sharp cutting blade by digging the point into the surface of the drip and lifting, take care not to go through the drip.
Another method is to use a blunt scraper with the corners rounded off and just rest it against the edge of the drip and give it a bump with one hand whilst holding it with the other hand keeping the angle low to the surface to prevent damage with the follow through.
Hope this helps.
