Looks like ZINC PEST which there is nothing you can do. Be happy you do not own some of the O scale trains that have ZINC PEST and cost owners $2500.....it's happening now!!!
The window deal may be more the zinc swelling and moving.
Toss it or live with it.......nothing you can do to fix.....raid for parts
As a 5 year old I started building plastic models. I built everything......and if I could talk Mom into buying it......I built it.
Early kits I recall are Aurora 1/32 cars and sub kits. Cars and trucks are my main focus but I built a T-Rex skeleton the other day so I still like them all.
Monogram B-24 I built in 1970;s..........my cat 'shot' it down and is no more
Hank called the process 'Psycho Swirl' in the old MC articles. Pretty simple. The car body can be any color but flat white works best.
Fill a bucket with water....hot or cold makes little matter. Bend a wire coat hanger to hold body so you can place it under water...or use whatever works for you. Spray whatever colors on top of the water AFTER the model body is at bottom of bucket. Spray your top colors, make any designs and pull the model up through the floating pant, with damp paper towel blot out trapped water and make paint conform. After FULLY dry clear coat.
About it.....Enamels work better as lacquers tend to dry to fast and kinda fragile.
'Sponsor' is not what is going on here......R2 is a licensee pf Coke or Hostess etc kits. R2 PAYS to make these kits and thus the brand needs to be popular and have a collector base. NAPA might not be 'collectible'.....
Never seen one in 1/25........Like a all new 65-66 kit in 1/25. One tool could produce a number of kits. Stock 65 and 66 2+2, both years GT 350, GT 350 H, GT 350 R...........I'll supply the 1/1 for reference!
For plastic I'd buy Evergreen or Plastruct.....the stuff sold with the machine is WAY to costly. Any thing Evergreen or Plastruct sells will work.....clear or white.
I made over 300 window units for my resin kits I sold years ago on my home made machine. If this was around back then I may have bought one.
We drove by that building often when we lived in Whittier and Dad worked of Santa Fe St in LA.
When I went back in 1997 after being gone almost 20 years I was happy to see it still there. There was a big show hall across the street that held a lot of car shows. Dad was Valvoline racing director so we went there a lot!
Change is the only constant.
OK....the JoHan kit was used to clone the MPC body.....all body parts interchange.
This is a mix up of JoHan parts and MPC.....MPC body, hood. JoHan interior and promo chassis. JoHan front grille bumper and rear bumper.
