Hi Guys

I have a old tiger tank that I would like to strip the paint off and start again. The reason I want to is because there must have been some oil on the plastic when I painted it last time because it has seeped its way through and all you can see is there oil stain. I used auto primer and it still seeped through.

Is there anything that will strip it off to get back to the bare plastic? or is there something that I can spray which will lock the oil stain in and not have it reappear?

any help would be great
