Finishing a model......HELP

Thanks....I was hoping to avoid doing this. Here's the history.....the model was old and done by a kid...I picked it up in a box free at a garage sale. I took it all apart, and re-did it (nothing had even been painted, just GLUED together). I am painting a two-tone paint scheme with a metallic sage green over silver. I had painted it all silver, sealed it with Future, then masked and shot the green on the top half of the car. When I peeled up the mask (Frisket paper), up came chunks of the silver paint. I tried touching it up, but it didn't work well enough. I tried sanding, the remasking (with low tack tape) the top and re-shooting the silver. It worked, but the irregularites of the pulled up silver still remained. I was hoping not to have to strip all the paint off to make it work. No luck I guess!!!
Thanks for you advice,
Sammy

First of all, get some brake fluid and strip the old paint off with that. A word of advice though, test on a scrap piece first....if possible from the kit being stripped. I've had a nasty surprise once when a whole body just melted into something resembling an ill tasting chewing gum Depending on how old the paint job is it takes different amounts of time to soften the paint, but it shouldn't take more than a week. A fresh paint job takes only over night to get rid off. I don't know if Future is good to use as a primer, I'd go for a real primer such as Tamiyas grey and white spray can primer. If you're not familiar with this range of paint the grey one is heavier and covers irregularitys better and the white one is for the last primer shot before the top coats goes on.

Good luck!
