Question about side molding...

I have a 90 model ST... i need to know if the side molding is held on by screws... or with a sticky material... and if its held on with the sticky stuff... when you take it off and get all the sticky shit off the paint will it leave behind any lines? i have a eraser wheel and access to some laquer thinner to remove the sticky stuff... and i also have some 2500 gritt buffing compound to blend the paint together... should i have any problem?
