hello all. this is my first time posting here and im hoping someone can give me an answer to my question. i have a 24" SE Racing Floval Flyer racing cruiser with a aluminum frame that id like to paint.
most forums ive been to talk about stripping the frame completely of its old paint. then they mention how aluminum is not a very porous metal so i would need to apply a chemical to the bare aluminum to open its pores so that the primer has something to "bite" into.
my question is this..instead of stripping and then treating the aluminum with that chemical...couldn't i just lighty sand the surface of the existing paint to get a slight texture that it would make the paint "porous" enough for the primer to hold? then apply the primer directly on to the sanded paint. followed by two or three coats of paint. and then a layer of clearcoat. i just want an option to the harsh chemical method. would my idea work well? would the paint hold up well? any ideas or suggestions are welcome and appreciated. thanks.
