ClarkM Posted February 7, 2015 Posted February 7, 2015 I stripped paint from a body with brake fluid and am just wondering if that will effect the new paint being sprayed on and if so what can prevent it. Any help would be appreciated thanks!
Snake45 Posted February 7, 2015 Posted February 7, 2015 A good washing in common rubbing alcohol should remove any residual stuff.
Greg Pugh Posted February 7, 2015 Posted February 7, 2015 I'd do both actually! I'd start with the alcohol like Richard suggested and then follow it up with a nice bath in some warm soapy water, rinse and then dry and you should be good to go!
Ace-Garageguy Posted February 7, 2015 Posted February 7, 2015 I ALWAYS scrub stripped models with Comet and plenty of hot water, with a toothbrush. Then, I ALWAYS thoroughly clean the model again with 70% isopropyl alcohol (available at the drug or grocery store, cheap). If I do these two steps, i NEVER have any problems.
Ace-Garageguy Posted February 7, 2015 Posted February 7, 2015 (edited) what about soaking it in soapy water? Depending on what kind of soap you use, it MAY leave a residue. You won't know until it fisheyes all over, and you have to strip it again. I started using 70% isopropyl as a final-cleaner on real $10,000+ car and aircraft paint jobs. We can't waste time and money stripping them if we go oopsey woopsey. Edited February 7, 2015 by Ace-Garageguy
JohnU Posted February 7, 2015 Posted February 7, 2015 The Comet cleanser scrub idea is a great idea! It cleans and acts as a light abrasive and gives a little tooth to the plastic for paint or primer to stick to. Dawn dishwashing liquid is designed to cut grease and oil. Heard somewhere that volunteers used it to clean rescued animals from oil spills!
LoneWolf15 Posted February 7, 2015 Posted February 7, 2015 Use the Original Dawn Blue , has no additives , will make it squeaky clean and ready for paint . I'd use a toothbrush and warm running water to scrub it down with .....
rsxse240 Posted February 7, 2015 Posted February 7, 2015 I am a mechanic by trade, so brake fluid cleanup is a regular duty in my line of work. Since good ol dot-3 is extremely hygroscopic, the best thing to use for cleanup turns out to be warm water, soap will help get any oils or contaminants from the plastic, then a wipe down with isopropyl alcohol (not rubbing alcohol as it has oils and moisturisers).
Snake45 Posted February 7, 2015 Posted February 7, 2015 ...isopropyl alcohol (not rubbing alcohol as it has oils and moisturisers). Never heard that. Where I come from, those two terms have been used interchangeably all my life.
Ace-Garageguy Posted February 7, 2015 Posted February 7, 2015 Never heard that. Where I come from, those two terms have been used interchangeably all my life. All ya gots ta do is read the label. Some rubbing alcohol "products" have additives...kinda like pasteurized-process-cheese-food "American Cheese" isn't really cheese, you know?
Mike_G Posted February 8, 2015 Posted February 8, 2015 (edited) Never heard that. Where I come from, those two terms have been used interchangeably all my life. I've posted on this subject before, SOME 70% isopropyl alcohol (usually labeled as "rubbing" alcohol) contains lanolin and/or fragrance. Lanolin can cause fisheyes and other adhesion problems and has to cleaned off with alcohol (I know, the irony) I usually use 91% isopropyl alcohol or pure denatured alcohol- no worries with either of those, but they are very strong Edited February 8, 2015 by Mike_G
Snake45 Posted February 8, 2015 Posted February 8, 2015 I usually use 91% isopropyl alcohol That's what I use. I use it for a LOT of modeling tasks. I'm pretty sure I could thin Testor enamel with it for airbrushing.
