Please , to save youself allot of heartache , please use primer . The extra cost is well worth the protection . When Resins were a new thing I had a bad experiance . I latched onto a '50 Hudson two door sedan (I don't know which model) . John Hier made it . I soaked in Whestleys , primed it and painted it a dead on match for the contemporary Hudson I was replicating . These were days before MCW . John Hier was offering a few colors in Lacqure . I clear coated it . Much drying time inbetween . I think it took a year to paint . I chromed the windows out with a brush .
Now , I moved on to about my third attempt of foiling . The first for large areas like the side chrome trim . Worked super . Got it all done and went ot remove excess . Large portions of the paint job came off with the tape (foil) . I haven't done foil since . I had not primed the body with adhesion promoter . You must use it under the first primer . it is the same stuff used on flexible body parts on 1:1 cars . Our Resin kits are the same material . All that work for .......! I will take pics and post throughout the modeling community . I will strip it some day and do over . I resist major (back to the start) as long as possible when I hit a certain spot in the build , like the end . Especiall;y when i cannot get the color of paint again . Thanx..
