I bought a can of Pelucid last year.A guy I know sold me on it by taking a bait and throwing it on his driveway several times without scratching it up.( I know ,sounds too good to be true)Here comes the but, I transfered a small amt.in to a small mason jar and when finished using it covered the top with cling wrap before placing the lid back on TIGHT,and placing it in the fridge.It still set up on me.plus I had some problems with the paint running on me with ONLY certain colors??? Mostly reds and purples.I was painting w/oils at the time so I switched to acrylics and SAME THING.I has a real high gloss and seems like it is plenty tough enough and the fact that it is one part was great.I use a product from a hobby store called finish up,or finish coat for clear coat on boats.The Pelucid works fine over another epoxy,but why would you need to do it w/2 different products? Its not real expensive so give it a try maybe you'll have better luck.
