I’ve only stripped one model before now... I gave it an overnight soak in paint thinner because it’s what I had on hand. The paint came off, but only by scrubbing with a plastic bristle brush + a LOT of elbow grease.

Some paints are easier than others. Tamyia is a bitch.

Hi,

I have very good experience with German Revell and British Humbrol colors. The coating effect of Humbrol is a bit better than Revell. But both are very well on plastic and resin, respectively.

Attached are my two Defiant sisters in NX and NCC-74205-A version. Buid them aprox 5-6 years ago...I got them from the Spaceboy. He WA also so awesome to print me some extra decals for the A version.

Greeting,
Michael

Pinhole troubleshooting, cont’d...

The good news, I’ve gotten to see how well Simple Green can strip paint. It worked like a charm! I got most of it off after an 8 hour soak, then put it back in overnight and went over it again with a toothbrush:

Unfortunately, the pinholes are in the model itself. I guess I did notice some grit/pitting to begin with (confirmed after reviewing my previous pics), but for some reason it became more noticeable with each subsequent coat of paint. So I went at it again with file and sandpaper to try and smooth them out as much as possible. Those concentric circles on the bridge module and ventral sensor array were too hard to sand down without mutilating them - so I just filled them in.

I’ll try another coat of primer to see if I succeeded in eliminating the worst of it. 🤞🏼 Stay tuned!

At first the re-priming seemed to turn out fairly well - most of the pits have been smoothed out but the model came out looking pretty scarred up nonetheless:

I stubbornly tried to do another base coat in light flat aircraft gray, and it looked bad. So maybe it is both pitting and a paint reaction? I threw it back in Simple Green and stripped it all off, along with half the primer. I may set it aside for now; I hate to just scuttle it.

I’ve also been working on the little Valiant class escort and it’s going pretty well - I am working on touch-ups and playing around with the color scheme:

The base coats on the Defiant and my “good” Gallant escort are done and I started a bit of masking work on the latter:

That one needs Mr Surfacer 500, bad. Such pitting bespeaks of frothy resin.
