RE: Gas-proof flat clear for protecting acrylic paintwork?
Klass Kote!!! Love the stuff!! Hate the price though!! If you happen to find some of the old K&B part A then the KK part B usually works very well with it. The Lusterkote works OK on most paints if you spray it on in several thin coats and let it harden for about 10 days. Longer the cure time the better it gets!!
