so i'm going to attempt to fix up the bumper since i have a bunch of chemicals sitting at the house that i should just get rid of a few sheets of fibermat, 3 cans of resin and 5 little tubes of hardener. did the first matting last night. used 2x2 inch mat squares and 1/8th can of resin with almost 1/4 tube of hardener. CUT THE SQUARES IN ADVANCE and apply with a soft bristle brush. a hard brush will cause the squares to move all over the place, and you want them to stay put when you are resin'in up. so cut your squares in advance. i cut 12 and overlapped them a bit. clean up the areas to be prepped, try to remove as much scale as you can, as well as bondo/panelbond but some of that stuff can be impossible to remove. i scuffed with a scotch-brite pad and then wiped everything down with a damp cloth. grab a soft bristle brush, i used a 1/2in diameter flat tipped brush. apply liberally. you want to double the surface area that you are matting, with resin. apply your mat, one piece at a time. use the opposite end of the brush to push it into the existing resin so you dont get it on your fingers. then paint over it with resin once it is in place. you want to cover the entire piece of mat, making sure to turn it from white to yellow. you can tell there are air bubbles under the mat if areas are lighter than others. once you are satisfied that you have full coverage and air bubble removal, lather rinse repeat. i was able to treat a number of areas with one application. enjoy! oh and dont bother trying to save the brush. i made a huge mess of my hands cleaning it with thinner and acetone. i'll just toss it next time. tips tricks comments welcome.
