That looks P.F.G.

That looks P.F.G.

Thank you sir

Not sure what happened but when I sprayed the wing with Tamiya AS-12 it bubbled and started to peel when dry.
I believe the spray is lacquer and I'm not sure which primer I used. It could've been Rustoleum or Tamiya. I don't remember.

Making some progress on this build. I still have some details to finish on the flight deck but it's moving along.

 

[Down Time]

Yes, moving along alright, looking P.F.G.

Same bubbling and snake skin on the bomb bay doors.
I am at a loss as to why this is happening.

I don't have an answer to what I see other than to sand it down oh so carefully, scuff up the bare plastic with used 220 grit or finer. Spray the paint into a cup and work it on with a soft brush.

How much are you spraying down and are you doing one coat only ?

How much are you spraying down and are you doing one coat only ?

I do spray the whole thing in one coat. Maybe a couple of light coats is the answer? IDK
I have always painted in one coat and this is the first time this has happened. It is a different paint though.

Well ,
that crinkling looks like if an additional coat , or more , is sprayed over too quickly atop the first coat .
That stuff is mega-solvent heavy --> https://www.hobbyco.net/content/files/msds/86501-86532 msds as.pdf
and if it's overtopped too quickly there's enough solvent still in the lower coat(s) to push up thru the new film .
But ,
if that's only one coat I have know idea what's up unless you're spraying it on too heavy , which behaves the same , the surface starts forming a film while the excess paint beneath is still full of all that solvent that hasn't made it out

I know you let the primer fully cure , so we know that isn't the culprit , and that means it's not from a surface contaminate .

High humidity will do that too
Temperature extremes ,
Anything that causes the surface to dry much faster than the uncured thickness below it .

[TimM63]

Thanks Keith. I appreciate the help.
I spray outside and it's been 100+° outside. That could be it or I'm just heavy handed. LOL

 

[urumomo]

Naw ,
that high temp can definitely do it .
Super light coats might be necessary . Real fast passes .

1/48 scale bombers? Yeah, they're big. Pffftt…. you haven't seen any of the 1/32 scale bomber kits. Avro Lancaster, B-17 Flying Fortress, B-24 Liberator….

I really want the Lancaster and the B-17…
