Hey guys i've ran into a little setback and was hoping I can get some advice on how to correct this without starting over... if possible. I had the usual problem of paint bleeding into the masking tape, but something that hasn't happened to me before occured. The paint bled between the lines on the rear window.

Before I start scrubbing and dipping the parts into liquids I'd like to verify if this (the paint used) is acrylic or lacquer, as stated on the bottle.

I went through some search results and noticed enamel's and tamiya acrylic's were covered with regards to removing it from clear plastic, but I did not see lacquer paints mentioned. Since removing paint varies depending on what type of paint it is, what would be the best way to remove this one, assuming it's a lacquer.

I have used bottles of 91% Isopropyl and Purple Power that I used to remove paint off bodies. Is it OK to recycle these products and use on clear parts since small particles of other type of paint are floating within the liquids?

While I was searching through previous threads I noticed someone mention masking the windshield then spraying clear to create a barrier and prevent the black paint from bleeding. I'm assuming you'd use a clear that isnt glossy. If the clear paint bleeds into the windshield will it cause it to lose the clear appearance it has?

Thanks in advanced for your input fellas.

simply lick a little toothpic made in wood and work with it carefully and only when wet.
With some skill u can make miracles.

Not joking here, it reallly works.

For stripping lacquers, I always start with isopropyl. You will want to use a new batch, to try to keep the clear parts clean.

When spraying black on windshields to avoid paint creep like this, it is best to never let the paint get wet on the plastic. Spray it on in many, many light passes, and keep them dry. If the surface looks like it is starting to get a bit wet, stop and let it dry before spraying any more. Build up opacity slowly and patiently. If you allow the paint surface to get wet, it's nearly impossible to keep it from creeping under the masking.

if you try spraying clear first, the clear will still creep if you allow it to get wet- which is just as nasty looking as having the black creep.

Thanks guys. I dipped them into 91% isopropyl and the paint came off with the rub of my finger within 5, 10 seconds of it being submerged in the alcohol. I used a Q-tip to get the paint off cause my finger got super black when I rubbed the paint off. I've never spray painter the windshields of any of my models before, but I'll give these 5 windshields I have ready to paint a shot. Thanks again for your help folks.
