hi there
i am really glad you have joined here.
i have brought a load of your stuff, about a year ago.
it is amazing, at a really good price.
thank you
in regards to plasti-kote, at B&Q they sell a textured spray paint

this is the textured spray paint, they do various diffenrt effects

this is the primer, cant remember the exact one i used, but you do need to put the primer on before you can use the textured spray, or it will warp and eat away at the plastic.
thay work really well. my Amera Buildings look great.
the texture is a lot more grainy than the GW Roughcoat though

, but it is the best alternative i have found.
