    I can't seem to find any hard evidence that supports brake fluid at the DOT 3 level or lower doing any damage to the type of plastic that the side panels and fenders are made out of that Suzuki put on these bikes. If someone can send a link, that would help but as of right now, I don't think it will do any harm at all.

      you got lucky i guess, brake fluid is terrible for anything to do with paint, i would not even try it, i was just trying to keep fellow riders from ruining there parts is all, i do know it eats paint and leavs a residue
      it has fish oil, or some kind of oil? in it, and plasrtic soaks up oil
      u put it on plastic master cyls ect... it brings out the color,, i would steer clear of it any painter would tell ya that , even oil off your fingers will get into the primer,or bare parts

        tried it, didn't do much, polished up the old paint is about it.

          Used brake fluid on the tail and one of the side covers on my bike. Washed off the brake fluid with soap and water, then used common paint prep degreasing agent. No problems. The plastic is ABS I think and doesn't seem porous as near as I can tell.

            Nah, I'm not a big believer that this stuff is anywhere near as powerful as it used to be.

            Trust me, if I'm having to re-apply for multiple coats just to get the paint to bubble off I'm not to frightened of eating away at the plastic.

            As stated previously, I'd be way more worried about having brake fluid seep into my plastic and making it too slick to paint on ever again.

              I have been looking for a good answer for this and here is what I have found. People have done both of these for vintage interior car plastic.

              Method 1

              Spray with heavy duty oven cleaner, wrap in plastic and set in the sun. Do not let dry and paint should peel off. Works best above 70 deg.

              Method 2

              #7 bead in a blasting cabinet.

              Now these were interior pieces and did not have a clear or primer on them. Don't know how much of a difference that would make other than more layers to be removed. I would suggest taking care in trying any method. I have seen paint remover warp and bubble plastic and would be very careful if you tried this. Maybe acetone or lacquer thinner with some 0000 fine steel wool would work.

                Hi guys, this all sounds good-BUT as a spray painter with over 20 years practice the only way to get paint trouble free off plastic parts is sanding,sanding,sanding and just when you no longer think you have any fingerprints left,yep you guessed it sand some more! start with 180 wet and dry,get ALL the paint off with that then work down to 1200 wet and dry via 240,320,600,800&1000 grade paper(to eliminate all the coarser sanding marks) use warm water and washing up liquid(amaze your wives/partners with the amount of time you spend at the kitchen sink)as a lubricant for the sandpaper. When you are ready to spray go to your local auto parts supplier and ask for BAR COAT, this is a paint that you don't thin,just spray on and let dry then if you missed any old paint/polish whatever paint you put on won't react and blister(unlike your fingers!!!). Paint strippers soften permenantly the first few microns of the plastic which means that whatever paint you apply will never properly dry-even if you put 2 part lacquer over it, have a guess how I found all this out?. Sorry to put a downer on some good ideas but as I said after 20+ years in the buisness I've tried most of these things and all that works 100% of the time is hard work Sorry!!.Johnny

                    The covers I did for the 750... I just sanded down what was there to give it a good "key" & went over the top.

                        Plastic paint stripper here under the aircraft tab. No experience with the stuff so this is not a recommendation.

                          Well, all I can say is that I used brake fluid on the front fender and both side covers and the primer and paint dried without any problems at all. The only thing I wish I would have done differently was to put clear coat on it.

                            Not so good, after one day soaking, didn't touch the paint at all. The rest of it is really clean!

                            Going to try some oven cleaner next.

                              I was curious about that stuff as well, seems to have quite the endorsement from several here... hope it's not a "half-baked" idea

                                Thannks for all the input guys...

                                I appreciate all the thoughts, suggestions, warnings & empirical testing you guys have offered!!

                                Using chemicals to remove the paint certainly seems like the easy way to go (better living through chemistry), but it scares me a little. I'm the one-in-a-million guy that would have all my plastics melt before my very eyes .

                                I guess wet sanding is the "gold standard" of paint removal - sounds like work to me however.

                                But, I have all winter to get these pieces sorted out, as it's too cold here now to paint.

                                Thanks again for all the responses.
