Omni MX190 cleaner/dewaxer anyone using it?

[davek]

Am I using it right. I sand the car and spray this on the part and wipe off before I prime. .I feel that I can get the same result if not better with Lacquer thinner. Im not a car painter and thats why Im asking. Does lacquer thinner leave a residue,chemical reaction? Just not impressed with the omni cleaner. thanks Dave

I just dont want to get it primed and have problems.

I don’t use Omni anything after delamination issues.

dont clean with thinner.....

never used omni, but I doubt their wax and grease remover is any different than the others..... I'd use it without hesitation

wipe it on wet and wipe it off thoroughly .......... allow it to evaporate completely after wiping, it's fast but will vary with temperature and air flow

You should use it before you start sanding also. Then before primer. Yes it seems like it's not that good and doesn't fully wipe off. Painters swear by it. If you've ever had contamination under your paint you will know.

I like lacquer thinner for a first wipe down. Painters say it not helping and may be hurting.

please explain, Im using omni epoxy primer and The fenders I sprayed in the beginning of this year and have no problems.

I had 2 horrible experiences with Omni base/clear peeling. One daily Honda- within a couple years. And another orange 71 camaro clearcoat blisters within garaged, reassembly months. Applied by-the-book.

Your results may vary.

Wax and grease cleaner is for use before you sand. If it stays wet for more than 30seconds, its too slow.
After priming and sanding, use a final wipe product.
I did find a lower cost product at NAPA that works as both. Made by G.R.O.W. I use it on day to day stuff.
But I concur, no Omni anything.

how about just using acetone?

I used PPG DX330 and then Shopline WG remover. It’s fine. Use it a lot in all stages. Never any issue. I’ve used Kleen Strip brand, Montana (whatever that is), SPI…. Never an issue. It’s W&G remover, can’t image it’s going to blow your project up. Why are you not impressed?

 

[davek]

I paint houses and when I spray a cabinet you could run your hand on it and your hand would be clean. I feel when I spray the omni and wipe it seems its not completely clean.

 

[69L48Z27]

Hmmm. I’m not sure I’ve looked at it that way. After sanding, cleaning seems like a never ending process with auto body. Sometimes I’ll wash the parts with dish soap solution, blow it off. Then W&G with some lint free towels, wipe in one direction. I’ve even used Sprayway glass cleaner sometimes after that. Then tack rag while blowing into the rag. I don’t think I’ve ever wiped a car or part only one time to get it clean. But, one round of W&G won’t clean it.

I always thought that was the ticket. I use a type of brake clean that doesn't leave residue. The body guys cringe, but I think it's just because they aren't mechanics

It could be cross-linking and melting whatever the surface material you are wiping too. Try a pre-paint cleaner like Transtar Speedi-scat.
It evaporates like lightning.

I use windex and microfiber towels. I have a towel that I spray with windex to wipe on and then wipe off with a clean towel. I change towels often and quickly blow dry the area to help the windex to evaporate off as fast as possible. If there are joints that it looks like the windex settles into I will go over them with a scotch brite pad to remove any residues that could have accumulated there. I used to use lots of klean strip wax and grease remover but had some delamination issues. I think people overdoing it with the wax and grease remover is a cause for lots of delamination issues. Epoxy primer is really sticky and forgiving stuff

also btw I am using single stage omni on my project I am painting and am quite happy with it so far. Seems really durable and has adhered very well so far.

Wax and grease remover with a microfiber can cause issues.

Thats why I use windex. I've also followed after the windex using a rubbing alcohol/distilled water mix if I want the panel crazy clean.

Little late to the party but we used alot of PPG / Omni products in our shop with good results.
Not to say in 20 plus years we never had a issue but after we most every time would find a outside problem.
Some of the OEM Toyota, Honda, used a strange release agent in their molds for bumper covers and would require extra steps to get ready for epoxy.
Prep is the key no matter what your product brand is. I see alot of guys never mention a good old soap and water wash and dry before a grease and wax remover is used.
Clean, New white never used cotton lint free shop towels for the wipe downs.
There are also some new nice disposables on the market now.

After our wipe down cloths were once used then turned into general shop rags never to be used in the booth again when washed they were dyed blue.
I've never mixed products , I stuck with one brand through the job. Not saying you can not get away with it but sooner or later it will bite you in the ***.
Many good brands on the shelf just stick with the one you choose.
Omni grease and wax remover is fine, use the proper thinner for product reduction not wipe downs.

DaveK. I see you say you are spraying it on. I have never sprayed it. Douse a clean cotton rag with it and wipe down the surface followed immediately with a dry cotton cloth. You should precede w&g remover with a soap and water solution to get the panel free of sanding dust. I try not to touch the panel with my hand after w&g remover because oils in your skin can cause paint issues. A light tack cloth to get any residual dust and rag fuzzies and then paint.
