FORMULA PYLON PART TWO month Ill present Part Two finishing Formula Pylon Racing plane Gary McPike Now primer sanded off its time think about colors Choose colors carefully recommend using light base color medium trim recommend dark colors hold heat can fry radios melt wing foam left out direct sun too long Maybe good time stop talk about paint may painting model epoxy paints K&B Superpoxy Hobbypoxy perhaps Pactras Formula U However several builders around country using automotive acrylic-enamels acrylicurethane paints Automotive paints have both advantages disadvantages feel advantages outweigh disadvantages long shot colors choose see great color car just go automotive paint dealer buy quart will pay about nine dollars quart opposed $2000 same amount hobby paint Automotive paints less critical far preparation atmospheric temperature humidity concerned An automotive paint shop does shut down too cold raining paint manufacturer has developed additives cold wet weather can find everything paint retarders accelerators hot cold weather manufacturer markets fisheye preventer some additive wet weather have painted planes great results real fog thicker spray gun fog can get special blenders will melt fresh overspray repair works well can find patch job dry major negative factor about automotive acrylic-enamels fuel-proof against high nitro fuels using final clear coat acrylic-urethane cover paint give plane high gloss get best both worlds much written about paints decide try should some experimenting reducers additives paint use Ditzler Delstar Acrylic Enamel two-part paint additive necessary unless going paint several colors coats short period time unlike cars get coat force-dried 1800 four hours before being driven out door have found double additive works well increases gloss totally fuel-proof urethane Ditzler good automotive paint market paint manufacturing company has acrylicenamel acrylic-urethane available As suggestion someone might like try type paint would recommend going several paint stores asking questions find someone doesnt throw Out door pump him dry Find out what common paint area use brand leave what paint Use whatever feel comfortable However no substitute careful preparation paint will show everything under try fill nooks crannies building mistakes paint thinking can sand smooth primer base color coat think again paint
