Suggestions prep resin body for paint.


Recommended Posts

Hello. I`m sure it has been covered before but i had no luck in the search history.

Here is the thing and it`s getting really frustrating. I have several builds stop because i have problems clean

resin body`s. Not as in removing extensive resin but actually get it clean of the mold release goo/stuff.

I have tried first to let it soak in diffrent soap from mild to heavy over night,then clean with toothbrush

and warm water,not too hot water. Then i tried isopropanol and cotton pads,rubbing,first light,then

more hard,but i dont want to rub to hard in fear the resin will snap or crack.

After the isoproponol treatment i then cleaned with water and soap again. I have now done this over

5 times,i`m not joking,and now i`m getting kinda annoyed because it`s still kinda greasy lol. I`m sure

there is somthing i`m not doing right,can anyone give me any good advice? Somthing you know will work.

Thanks

Tommy

If you can get it in Norway Tommy, Super Clean will clean them up as clean a a whistle in no time.

A lot of resin casters will recommend things like Super Clean, (or a different brand like Purple Power) to clean mold release agents.

I believe some guys use "Wesley's Bleche White" also.

I won't vouch for it as I have not used it.

I've also heard some people swear up & down that just a good scrubbing with warm water & dish detergent is all that's needed.

For me, the Super Clean works fantastic for removing nearly everything from plastic or resin. From decals & chrome plating, to automotive lacquers.

I have a perennial tub of it in my shop at all times.

A good scrubbing with warm water & dish detergent does not work on these body`s. All those names sounds familiar

but i have been told the products will melt the resin. Those who are so strong it can remove paint on styrene that is.

Not sure if there is any truth to it. This is the problem,so many rumours and sayings that i get confused.

They do not sell those products here. I have tried searc all over the place. Amazoon will ship those small squeeze

bottles,i was hoping to buy a gallon of either Super Clean or Purple Power.

I have seen what Tommy has experienced with a lot of Jimmy Flintstone products . You definitely need a STRONG "Degreasing agent such as Simple green, Westley's Bleech White , Castrol Super Clean or something for Tires .

The ones i struggle with are indeed Flinstone products. Two stationwagons.

The Imperial is resin,yes? The Super Clean you mention is this what is called Castrol Super Clean?

Actually The Imperial is styrene, but I have soaked resin for several days as well with no ill affects.

I don't believe the Super Clean carries the Castrol name anymore, but here's what you're looking for.

Tommy, look for any cleaner that has the name "trisodium phosphate" on the label as an ingredient! This is also often called simply TSP, and is a tremendous detergent, often used for general cleaning, such as mopping floors, etc. TSP will dissolve any greases, oils or silicones and remove them from any surface--and it absolutely will not harm polyurethane resin.

I bought a gallon Purple Power and two bottles of Scalecoat Model RR paint wash away stripper. The last said

to be very good,this based upon rumours only so will see. I`ll get back on the results when i try it out. Thanks

for ideas and suggestions.

I did not find any good pinned threads on resin-prep or paint remover on here?

I have a feeling that you're using a dish detergent that has something in it to protect your hands! Same thing they do in 70% alcohol - they put in something to take the edge off the alcohol when using it for rub-downs. If you look for a detergent that has no extra ingredients, you may find that it will do the job.

However, I was reading a back issue yesterday and there was an article on resin kits and preparing them for paint. Granted, the article was from about 10 years ago, but I imagine the problems are still the same. Anywho... the writer said that you should clean with lacquer thinner, then with mineral spirits, then with detergent and warm water. I'm sure he was trying to cover all the bases! B)

Hmmm... I have used Scalecoat, and their paint is kinda wierd. I would not be surprised if their remover doesn't work all that well on other paints... :wacko:

Thanks for all the suggestions. I`ll have to try and see if i can get my hands on Super Clean.

It's available at Amazon - just found it this am... BTW, it's not called Castrol Super Clean any more - just Super Clean. Purple Power came up in the same thread.

From what I've heard Tommy, Purple Power is pretty much the same thing as Super Clean so I think you should be pleased with the results of using it.

It is, after all, a degreaser.

If it will remove automotive lacquer, it should take care of most anything.

Steve

Yes i was told those two where close to identical. I`m really excited to try it out so i can get started on strip old builds

and clean these resin bodys.

I have a feeling you are making assumptions. The alcohol is 99% pure for medical use. It clearly says use protection when using it.

The softer type of soap was used in the end,the soaking and rubbing i used oven cleaner,also somthing you are required to use

glows on,or it burns your skin,dont ask me how i know.

I will not use lacquer thinner on resin.

I've had nothing but good luck using Westleys Bleche White to clean the mold release agent from resin parts and bodies.

DON'T USE SCALECOAT ON MODELHAUS RESIN STUFF...... IT WILL MELT THE RESIN...!!!!

Good to know,thanks.

If it melt resin it should bite good on styrene. I cant get hold of Westleys here,but i now have Scalecoat and Purple Power to try.

Make sure you use gloves with the Purple Power as well Tommy!

While it won't hurt the resin, it will hurt your hands! :)

I have a feeling that you don't know the difference between opinions and assumptions. Sorry I bothered... :angry:

I do know the diffrence between opinions and assumoptions,and this is not an opinion.

Anyway,this is irrelevant,if you have somthing you do know work well for cleaning resin,feel free to share it.

Been testing the Purple Power stuff,and here are some experiences so far.

It strips chrome like a champ and also does not harm resin. I soaked 3 resin bodys for 2 days,no problem at all.

It has no effect on Tamiya metallics,also there is close to no effect on certain solid colors. Have been soaking some

old build-up`s. I assume it would need to be soaked several weeks for any effective strip. I dont have patience for

such so i will be getting Scale Coat paint stripper for more aggressive treatment on the styrene parts.

I used Humbrol Acrylic Thinner to wash the Tamiya metallics,it works but is time consuming and the smell is horrible.
