Hobbylinc #HLC107. INSTA-CURE+ is a higher viscosity CA for loose fitting joints in which the adhesive must bridge gaps. Normally, the thicker CA is applied to one surface and then the parts are held tightly together for about 5 to 15 seconds. For large surface areas, including those with close fitting joints such as laminations, INSTA-CURE+ should also be used. To prevent premature curing, don't spread the glue into a thin film. Lay down a serpentine bead with about 1" separations on one surface, then assemble the parts, letting the pressure spread the CA out. .

Hobbylinc #HLC113. MAXI-CURE extra thick CA is the best CA for most plastics, including GE's Lexan MAXI-CURE is the best choice for plastic model assembly. When used with INSTA-SET, it works better than any putty for modifying or filling voids. It can be carved with a knife or razor blade and sanded and feathered to form a finish indistinguishable from plastic. MAXI-CURE bonds fiberglass, hardwood, metal and rubber better than any other hobby adhesive. For gluing to the inside, cloth-textured surface of fiberglass, scrape the area to be bonded with a razor blade or coarse sandpaper before using MAXI-CURE or any other adhesive. It also is best for bonding the tires for R/C cars.
