Today I went out searching for something to remove any spray wax on the original vehicle to check to see if any evidence of OptiCoat was left below. The product I ended up getting was Rustoleum Wax and Tar Remover. This product states its designed to remove wax, tar, grease and road film.
I decided to use this because it's designed exactly for the task at hand (removal of spray wax) and it says it's safe for auto paint. So, it shouldn't strip OptiCoat right? This turned out to be a great product. Its not solvent like, but kind of soap like. It has a faint soap smell, and I had no problem using it without gloves.
First, I rinsed the truck down with a pressure washer. Then I dried it with an air sprayer. Then, I did a waterless wash using Opti Clean. I did all this at the local DIY car wash, as the sun is hot and I can work under shelter there.
After that, I proceeded to wipe the truck down 3 times over with the wax remover. I did not remove the spray wax from the glass or the sun roof with the wax remover. I left it on there purposely as a comparison surface. Each of the 3 times I used different and multiple towels to apply and remove the wax remover. This worked great and removed any wax that was topping the "coating" for sure. You could tell by feel before and after the topper wax was removed. Surface was "squeaky" clean. This took about 2 hours. Finally I knew I had a vehicle that had one of two things on the paint:
1. Opti Coat
2. nothing(or close to it)
Then I resprayed the vehicle down with water to check for any signs of beading or sheeting. The OC was applied about 5.5 months ago. Prior to applying it, I polished the vehicle with the Wolfgang twins and did a thorough IPA 20% wipe down multiple times after the polishing. I used 8cc of OC for the whole external vehichle, minus glass and wheels. I applied the OC with a piece of the supplied yellow foam applicator. After OC application, the vehicle was not washed for a week to ten days.
Here are the results when I stripped the surface with wax remover and checked for any sign of OC left on the paint (keep in mind all glass has Optimum Spray Wax on it, but was never OptiCoated):
To me there was no sign of sheeting or beading to say *any* OptiCoat was left on any surface at all. My Opticoat went up in Opti-smoke.
About 70 hours prior, when I first noticed there may be an issue, I decided to strip the hood only. I stripped it completely with Sonus APC and Griot's Paint Prep. At this time, the rest of the vehicle was covered with spray wax, and I was hoping this issue was only limited to the hood.
At that time, I had about 1.5 cc of Opticoat left in the original syringe. So, after stripping all the spray wax of the hood, I again did an IPA wipe down. This time. I wiped it down with 20% about 10 times using different towels. After that, I wiped it down twice with 91% IPA. I then wiped down that with DI water.
At that point there was nothing left on the surface. Wolfgang Finishing Glaze was not in the equation this time. I then applied the 1.5ccs of OptiCoat I had left to the stripped hood using a fresh 1/4 of the supplied yellow foam applicator that comes in the OC kit. 1.5ccs was just enough to coat the hood.
It "cured" untouched for about 70 hours. Nothing was applied to it after. I know OC was on the surface, as when I initially rinsed the truck, the hood beaded like crazy.
Here is a pic of that:
I then applied one wipe of the Rustoleum wax and grease remover to the right side quarter of the 70 hour ago OptiCoated hood. To my surprise, the hood beaded and sheeted well, all except that quarter! It seemed as the wax remover killed the OptiCoat!
Here are a few pics showing that. Notice there is a clear demarcation where the beading stops, and water just lays on the surface ( right side of hood / picture ). Also, keep in mind this is the SECOND time this surface was OptiCoated in 5 months:
This was after the OptiCoat "cured" at least 70 hours on the surface. It seemed to be easily removed by wax and grease remover. I thought this stuff was much tougher than that. I thought OC was as permanent as clear coat. I believe Optimum says you can wash the car a day or so after OptiCoat application without affecting it.
This wax and grease remover did not seem like a strong solvent, more like a soap or a paint prep. Actually, it says it's safe to apply on a base coat prior to applying top coats. So, to me that would mean its not strong enough to remove recently sprayed paint.
I did a littler more research on this wax remover product from Rustoleum and found out its little more than soapy water with some ethanol derivative in it. From the MSDS of Rustoleum Wax and Tar Remover:
The following materials are non-hazardous, but are among the top five components in this product.
Chemical Name
Water
Ethanol 2,2 iminobis-N[3-branched decyloxy)propyl] derivs.N-oxides
Pennsylvania Right-to-Know:
CAS Number
7732-18-5 68478-65-9
The following non-hazardous ingredients are present in the product at greater than 3%.
Chemical Name CAS Number
Water 7732-18-5
I also found out that “Ethanol 2,2 iminobis-N[3-branched decyloxy)propyl] derivs.N-oxides”, with a CAS number 68478-65-9 is used in many cleaners, and is described as an “amphoteric surfactant”. So, yes, it’s basically Rustoleum soapy water.
.... And this took off Opti Coat???? Two coats 5 months apart???
So now I don't know what to do. I have a paid for syringe of OptiCoat and a liter of Erasor arriving Monday. I no longer have a lot of confidence in the product, in the sense that its as long lasting for me as its designed to be. Prepping the whole vehicle and reapplying it is a whole lot of work, no to mention the cost of having to re-purchase the product. I could have got this length of protection out of a regular sealant and or wax.
Even if the OC is still on the surface, I can see its not sheeting or beading water, so I'm not sure what the point of it would be. Maybe you could say the failure of my first application 5 months ago was my fault, as the IPA 20% did not clean off any polish residue. But, I know for a fact 70 hours ago when I re-coated the hood there was nothing on it. At that point, I cleaned the hood with APC, Griots Paint Prep, and did no less than 12 IPA wipe downs, with the last two being at 91%..... And it seems to be once again gone!
A few questions:
1. At this point, I'm thinking of just giving up on OC, as I have little faith in it. Has anyone had a situation where they asked AG to return an unopened item. As I have a syringe in shipment that I'm not that interested in using at this point. Maybe I could trade it on the sample thread for something good.
2. Has anyone else had this happen? I mean, most of us are probably using spray waxes or similar as drying aids on Opti Coated vehicles. These products will usually bead at least until the next wash. I was re-applying them after every wash, assuming the OC was still safely on the surface. Has anyone "stripped" the spray wax off their vehicle only to find no evidence of Opti Coat left?
Any feedback is welcome!
