Ray do you have a recommendation on product for plastics like the bed rail guards, plastic bumper pieces, and interior plastics?
Yes, I have found products that clean plastic, or rubber, and leave it like factory new. They leave no slippery feeling, or fake gloss. The problem is, as with many of the products I use, they are not sold at the public retail level, only in the professional lines. So, it can be hard for the public to get them. And they generally only come in gallons, so they can be costly.
The original version, and still my favorite, 3M Prep Solvent-70, P/N 08983. (1 gallon). It is strong enough to actually be able to remove Armour All. Which was a nightmare for about 10 years, before this stuff came along.
An alternate, if you have a Sherwin Williams
automotive paint store in your area is, W4K157, (1 gallon). You can also get this product in a slightly diluted version, in a quart bottle, with a sprayer, as SC155.
I am certain Dupont, and PPG, (if they are the only automotive paint stores in your area), have versions of these, that work just as well, but I have not used them. Just ask for a water based prep solvent. Maybe they have quart versions? Martin Senior automotive, (NAPA), sells the exact same products as Sherwin Williams, but they use different part numbers, so it is confusing.
Because these have almost no odor, and are water based, they seem safe enough to drink. However, they are very powerful cleaners. They actually do a much better job than smelly oil based prep solvents. Unfortunately, most shops have not figured this out yet, so not everyone stocks them.
Apply these a with a well soaked rag, allow to sit a few seconds, and wipe off with a dry rag.
Do not leave a rag soaked in these products, sitting on painted surfaces for long periods of time. We have had beginners who think the stuff is harmless, because it is water based, leave a rag sitting on a painted panel, and go home. They can soften paint.
These products though water based, are mildly flammable.
That does not mean you will damage your paint, using them to clean your vehicle. They are specifically designed to be used to clean painted surfaces, and evaporate quickly, when allowed.
A gallon will run you about $50. But, it will last you the rest of your life, unless you start doing detailing for money.
If you can find someone to split the bottle with you, it is still going to last you a long time. The cheaper option, if you can get it, is the quart of SC155 from S/W, it will run about $15. As I said, it is diluted W4K157, but it is still up to the job.
If you want, you can follow this with a coat of vinyl protectant of your choice, I like to use the low gloss ones, like Meguiars #57, (a marine product, available at any boat store).
