Hi everyone.

One challenge I face is prepping plastic for painting with my airbrush. I am nearing the paint stage on my current build and would like to avoid the issues I have faced in the past (paint adhering to the surface of the model and paint running down the sides). I live in a very small apartment so big tubs full of warm water and Dawn liquid detergent don't work for me. I have considered rubbing down the model several times with isopropyl. Are there any other suggestions.

Thanks.

Alex

I've never washed any of my models before painting... but I have to ask... do you not have a sink?

I have a sink yet it's not big enough and I don't want to wash the model in the sink I use for preparing food items 8-). I used to live in a home with a huge utility sink. It was the best.

I never wash mine either.Only resin or white metal.If you have paint adhesion issues-try priming with Mr 1200 or Tamiya Fine in the rattlecan.This way you don't have to worry about knocking off parts while trying to wash down a model.

You don't need a big tub, do you? Plastic storage and food containers can be purchased at supermarkets and big-box stores. Or one of my favorites ... used plastic food containers. I try to repurpose anything in my path!

PS: I don't go anywhere near a sink/drain with all of those tiny parts.

Hi Alex,

Based on the space restrictions you describe, the ISO wash is
your best method.

Is that the 3ft u boat you are going to prep?

Cheers,
Joe

I seldom wash a model before assembly and painting. I agree with Anthony that a coat of primer, (I just love Vallejo's acrylic primers), will generally be all that you need to supply a good base.

Just a wiping down with iso alcohol to remove finger oils and grease is usually enough.

Hi Joe.

It is indeed the 3 footer I am building. It takes up some space yet it has been fun. I have some plastic tubs that I soak parts in isopropyl with. I am leaning towards the rub down with alcohol and using a good primer. Du to a convenient mistake, I have decided to build the U-333 after its showdown with the HMS Crocus.

Everyone have the best day ever. Be well. Alex

I ALWAYS wash the plastic before I do anything, then wash the sub-assemblies before painting. I use windex or formula 409 or similar grease cutters. Plastic kits are covered in mold release lubricant as they come out of the box, so must be washed well.

Just spray with your favorite surface cleaner, rise well and all should be OK.
