Ello,

I usually fuelproof my firewall etc. with thinned epoxy but I wanted to know if there is an other way to do it. Could you give me some tips and names?

BTW I live in Belgium (Europe) so most american brands wont be available here , but I am going to a big meeting in Germany next week (Intermodelbou Dortmund) so I will have a fairly big choice.

If it ain't broke, don't fix it.
Brushing a coat of thinned epoxy on the firewall is the lightest, best way to fuel proof against glo or gas fuel.

In short, keep on keepin' on.

Is it ok to thin the epoxy with acetone or should I use something else?

I used denatured alcohol when i did it

I am very sorry but I live in Belgium so english is my second languige (which you can tell from the typpos) and I don't know what denatured means. Could you explain it to me

Regular, over the shelf, alcohol. The kind you may be able to purchase at your local market. If not there, then at your local drug store/apothocary.

Another method for fuel proffing is to use any form of resin. It can be of a laminating or marine type.

Also useful is any type of polyurethane paint.

Epoxy thinned with alcohol is still the cheapest, and probably the easiest method.

Denatured alcohol is the same thing as Methylated Spirits
you should be able to get methylated spirits in a hardware or paint store.

It is not the same alcohol as rubbing alcohol or what you get in a drugstore for health use.

Denatured or rubbing, both work equally well for thinning epoxy.

I've been told that you should use at least 90% rubbing alcohol for thinning epoxy. The more common, in our markets/grocery stores, is 70% and that is reported to make the epoxy rubbery...

Rubbing alcohol is sold by varying percentages and I was told to use the 90% type. I am not saying that you should use 9 parts alcohol to 1 part epoxy for fuel proofing purposes...

BTW -- what is a good ratio of epoxy to alcohol for fuel proofing?

Don't thin epoxy! Just warm it up and it will flow very nicely. YOu can either set the mixing container in warm water or brush the epoxy on and then use a hair dryer to warm it slightly.

Thinning epoxy is a really bad idea. There are currently a couple threads going in these forums that explain why.

When I thin my epoxy to fuelproof, I just add enough alcohol to get it to the consistency of "hot maple syrup" for lack of any better thing to compare it to. Fairly thin, but it still has some "body" to it. Then just brush it on with an epoxy brush.

Oh, and make sure you use at least 30 minute epoxy to fuelproof with.

Thanks a lot for your help


Cafeenman, can you give me the threads?

I don't remember where the second thread is, but this one has good explanations by a couple of folks:
