Title: removing paint from porcelian Post by: scalebowler on October 26, 2010, 11:09:06 pm Will just any paint stripper work for taking paint off porcelain or are there some that are too strong? My gas pump has porcelain coated side pannels that I need to remove some paint from but I don't know what chemical to use.

I have acess to an industrial dry soda blaster and it works very well to remove paint without being to abrasive. Comes out very nice.

Going to get some paint stripper so that I can get the frame painted up before it gets too cold. Do you guys have any suggestions on a good paint stripper? I just don't want to end up getting something that does not do a good job at taking the paint off.

The color of true porcelain enamel is part of the glass beads/powder itself, & the paint stripper & solvents wont harm it at all , ( think of a colored/stain-glass window pane, you can scratch it, break it, but the color is part of the glass itself, not only a surface coating) steel wool will work with some elbow grease too as you've stated. Title: Re: removing paint from porcelian Post by: scalebowler on October 27, 2010, 09:39:14 pm How do I tell if it is truly porcelain? I did do some experiments with stripping the paint using PVC pipe cleaner which I think is mostly acetone and the finish is still shiney and red. (I origionally thought it was paint and was not too concerned with what happened to it) Is that a good test or not?
Title: Re: removing paint from porcelian Post by: aspbear on October 28, 2010, 08:34:49 pm If you did not get any color transfer to the rag you were using with the PVC cleaner then it is porcelain. The paint would give you some color transfer....
