Mark II for Metal. Not for use on fabric. Note: Do not use Mark II over fabric or on structures that will be covered with fabric cemented with New Super Seam cement or with Polytak cement. New SuperSeam or Polytak may lift Mark II.
Use: Mark II for Metal is available in the same 50 colors as Colored Butyrate Dope. Mark II is used over primed metal or composite parts and is too brittle to be used over fabric. Mark II is a tough, long-lasting topcoat paint. Although Mark II is a two-part-catalyzed paint, it is not catalyzed with an isocyanate, thus normal safety equipment (a charcoal filtered spray mask) is sufficient. You do not have to use a supplied air respirator when spraying Mark II. Packaging: Mark II comes in three-part kits: part one is a can of the colored paint; part two is a separate can with an equal volume of Mixing Liquid, and part three is a thinner to be used to prevent orange peel. Coverage: One mixed gallon kit (one gallon paint, one gallon Mixing Liquid) yields two gallons of sprayable paint. These two gallons will cover approximately 400 square feet with one coat. Mixing: Combine one part of paint with one volume Mixing Liquid. Let stand for 20 minutes to allow the catalyst to work. Thinning: For most conditions, try using it directly out of the can with no thinning. If orange peel results, thin 5 parts mixed paint to one part Mark II Thinner. Application: Spray two or three coats one hour apart.Two coats may be sufficient. Allow overnight drying before moving parts. Mark II takes longer to dry than one-part paints. It may be slightly tacky for 24 hours. Shelf Life: Four years in unopened storage. Important Notice: All mixed paints are special order and are non-returnable. |

Fully cured Mark II paint can be wet sanded for any imperfections.
After wet sanding with 1500, 2000, & 2500 grit wet/dry sandpaper you can use the 3M Perfect-It kit to bring the paint to a hi gloss. Poly Fiber also recommends using a carnuba wax as a final polish.
Yes, the flattener can be used with Mark II finishes.
No. The recommended primer for Aerothane would be Ep-420.
This is just the clear base.
Yes, the previous question was related to part # 09-03869 which is just the clear base that is used when mixing colors. Apologies for the confusion. If you order a color, it comes with the thinner and catalyst.
