Looking good Brian, nice seeing some paint bringing all that detail together! 😎

It looked great in grey, and sinister in black. Looking forward to the final (weathered) coat.

Cheers for the interest, a good bit of progress this morning, painting, chipping and some weathering marks added. I will add some more chipping later but want to add a few markings and decals first.

Love the vibe here...

It reminds me of those SF book covers from the 70s

 

Cheers,

Alan.

Looks like something from Red Dwarf

Oh balls...........

 

I skipped the gloss coat I normally do before masking. I won't do that again.

It seems to me that the problem is not the lack of a gloss coat, rather poor adhesion of polyethylene. If I good see all the paint is gone with the masking tape, so is the primer.

Ouch! You've got as much sympathy as I can send, Rocky. At least the stripes are sill intact?

[rockpopandchips]

Sometimes these thing come apart easily

 

 

And go back together OK as well.

PE polyethylene plastic isn't a thermoset so the individual atoms in it move albeit very slowly. As they move away from the surface the paint is no longer anchored. After enough of this happens the paint can be peeled off in a sheet.

Fear not there are two ways round this.

1. Rough the surface up to increase surface area then use a plastic primer (Halfords is pretty good) in two or three thin coats. As it dries it shrinks and it remarkably resilient.

2. Get some PVA as used by builders thin it to taste and paint it on the PE making sure it also anchors to adjacent materials if not completely covering the PE. Then your cheapie primer will stick well.

 

The latter was applied to the domes on my nephew's full size Dalek domes and 20 years on they're still good except where they've been scratched. You must be using a very tough clear coat to get the same effect.

 

That's come out very well indeed and looks fantastic, I'm glad you have been able to rescue it.

I will have to take your word for it, I just stick stuff together and paint it, with little regard for anything else...😁

 

I would normally use Halfords primary but used some stuff from the £1 shop, it's OK but obviously not good for PE and it stinks like hell. I have never thought about PVA,  I have 5L of the stuff left over from a DIY loft project...thanks for that.
