Default Fuel proofing

After running very rich with an 18% oil content.... wipes right off! USC Spraymax Matte Clearcoat 3680065 Its a sprayable 2 part epoxy clear coat. I'm sold on it. Also seems to toughen things up a bit as well!

Just used their gloss version for my boat cowl. It is a great product...BUT...it is NOT an epoxy but a 2 part urethane system. While older epoxies (like Klass Kote) are not good to inhale, this one is seriously bad. Make sure to hazmat suit up, get a respirator for organics, etc.
At $23 per can not cheap - and once you start to use it has a day or two pot life.
It is easy to apply, and gives solid protection.

It works very well Ted. And you do need to wear your BEST Corona Virus Mask for this! Long sleeves, gloves, Eye protection, etc. First can I bought a few years back was $16. Was up to $30 a month ago. Today around $25 with free ship on Amazon. Best to line up a few jobs for coverage and spray it all out because the next day it might not come out. Also, don't expect a new on shelf non activated can to work 2 years later.

While safety is at the top of my list, if spraying these products outside occasionally they are not going to have such a risk. IMO many will read the recommendations for a full hazmat get up and choose to use a different product with far inferior performance. IMO shooting 2K clear a few times a year with just a cloth mask is far less hazardous then a 1 pack a day cigarette habit. Of course safety is a personal choice so do what makes you feel comfortable.

Yeah, I'm gonna stick with 409 spray and paper towels. No SpaceX suit required. Installing a deflector on the end of my muffler helps too.
Cleaning an airplane never bothers me. Cleaning a toilet? Yeah, that's no fun.

Oh... my.... Criminy; I've shot this stuff in the backyard with rags wrapped around my face and crummy long sleeve shirt. I wear cheap old man glasses that I can afford to throw away. Just don't breath it and keep it out of your eyes. If you breath it and it gets in your eyes, the ER probably won't be able to do much.... Definitely outside use. Or don't use it at all. Made the video years back for all the times I had read rcgroups people asking what to use to fuel proof since RC Companies don't make fuel proof paint anymore. Thought I would share it here too. Cleaning out the kids computer and decided to post it up before I deleted it. If you can shoot a BB gun without shooting your eye out, you'll probably be fine.....
If you can't cut your food yourself, this Product is not for you.....

Each to his own about how much personal safety to take, I guess....
I still use acetone to clean epoxy glue off of my hands, and don't worry about the times I spray epoxy paint outside with no protection. So no nervous nelly.
But this stuff can do serious long term damage pretty quickly. If you can smell it, you are way over exposed. An automotive paint type respirator is a great investment, and given all the other costs for our hobby, not that expensive.
And while a spray suit might be seen as overkill, they are really, really cheap at the local Home Depot...so why not? Besides, they keep the dog hairs on your shirt from drifting into the paint job!
Me? I may use it again someday, but generally will stick to true epoxy fuel proofers, like Klass Kote, for my airplanes.

Most of my IC, Metho/Petrol or Kero powered models where there is a posibility of spillage I coat with 30 min. Epoxy diluted somewhat with Metho for easy brush application, few thinner coats does a great protection to ply-wood boxes or even Depron foam I use in turbine powered models. Acetone or Metho Spirit is a great cleaning agent I use on my hands, immediately washed with Solvo or soap agents after.

Well protected wooden engine mount box with numerous coats of thinned down Epoxy, after 10 years of operation. Now convert, to E-power! LOL.

Now silent and cleaner.

Turbine powered foamy fuel tank sump well protected with Epoxy coating, finished off with few coats of paint for 'estetiks'.

I used to do the thinned epoxy thing on my engine compartments and back into the fuel tank area. As I've become older and not wanting the kids to have to wade through so much old man clutter.... RC Hoard, etc..... when I pass, I've been using this old can of Sig Supercoat. It's a silver color and ensures everything I build gets silver Blech marks everywhere it shouldn't be and all over my fingers too! But its ready to use after a few stirs! Been using it in retract bays, Split Flap bays etc. Still a third of a can left. Had it so long I don't remember how I got it and it still may be there for the kids to toss when I die. Or use maybe????
