Maxi-Cure extra thick CA is the best CA for most plastics, including GEs 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, clothtextured 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. INSTA-SET is a catalyst which acts as an accelerator that allows CAs to quickly cure in thick layers by enhancing the alkaline conditions during polymerization. INSTA-SET in a spray bottle is normally used to cure the CA that flows from joints when parts are pressed together. Applying an additional bead of thick CA along a seam and then curing it with INSTA-SET significantly enhances a joints strength. For difficult to bond materials, INSTA-SET can be applied to one surface and CA to the opposite surface. When brought together, they will bond instantly. INSTA-SET is formulated with a strawberry scent and activates CA in 6 to 8 seconds without any degrading of the CAs strength, which can occur with many other accelerators. It is compatible with all surfaces, even clear plastic and white foam.
