Paint to use
 

Can anyone tell me if Aerogloss can be used over laqure or enamel like Krylon? I'm less than impressed with lusterKote and have never used monokote and don't have the tools to apply it.
Thanks:eek:

My first reaction would be to say YES, but don't take my word for it. What I always tell people is to
do a test. What a wounderful idea! Seriously, you can lay down a sample of your base coat of laquer,
or enamal. Let it dry for several days, and then apply the the Aerogloss.
With all the EPA rules and regulations, paint manufacturers are continually changing their products
to comply with new laws. As a result products that used to be compatable may not be anymore.
The best answere today is to do your own test. Good luck, Greg

Based on an experience with Krylon, I'd suggest that the test not just be with raw fuel, but also holding the sample in a nice hot exhaust stream. I had a couple samples hold up to several days exposure to raw fuel, painted a plane with it based on the fact that the paint held up, only to have the paint turn into a gooey, sticky mess in just a couple minutes of exposure to hot exhaust. In fact, I didn't even get the plane launched.

Apparently, there's a difference between just fuel proof, and what Aero Gloss used to call Hot Fuel Proof.

You might try an Automotive parts store for "HI-Temp" Exhaust paint. I think Krylon is one of the MFG.'s. This paint is used on Car Engines and withstands heat upwards of 500+ degrees.I don't know what colors are available now, but I use to get it in Silver, Red, Orange and Black. As for "Fuel Proof" Gas and Deisel fuel won't hurt it once it's dry so I doubt that glow fuel will. Hope this helps.

You should keep in mind, some people do not have money trees growing in their yards, and maybe not alot of time to waste on tests. Some people are just looking for a quick, money saving answer...not sarcasm. It could be that he does not have Aerogloss on hand and does not want to buy any just to test with, then come to find out... it is not compatible.

This is not an inexpensive hobby. Testing is not a waste of time. It is a valuable assist to our endevours.

In my opinion, if you cannot afford a bottle of dope for testing, you need to find another hobby.

Without testing, I'm just guessing, but I would say that you cannot put Aerogloss over Krylon. You may get away with putting it over lacquer, but I would suggest a test, first.

Here is a link to a small chart of the cpmpatability of the most common paints used in our hobby. This is a good site for reference.

The solvents in dope, like aerogloss, will not mix well with enamels. You might be able to overcome this with a sprayer and misting a few coats of nitrate dope (dries very fast) on the surface.

No fancy tools are needed for plastic coverings. Back in the early 70's I used my mom's household iron. It won't make you one of the "cool kids", but it does indeed work.

I didn't see any sarcasm.  And what is any hobby but something to take up your spare time?  (chuckle) I'd LOT rather spend a few minutes testing something to see if it would hold up than spend a couple hours painting a model, have fuel eat my paint job off, then take MORE time to get that mess off there and paint it again.  Testing a finish before applying it saves both time and money.

If you have some doubts, can't get a direct answer, and don't have the time, for paint compatibility a couple minutes a day for a couple days a week apart, to do a couple quick simple tests, you don't have the time to do the original job either. Spend a couple minutes at the start and make sure, or spend hours later. Some years ago, a lead engineer approached me about a cost reduction on a product line I was supporting. An MBA in purchasing decided we shouyld be using a 15 cent 5 Volt regulator for our project instead of the 85 cent part we were using in production. We shouldn't need to test because the data sheets showed they had the same parameters, so testing was a waste of time and money. He had been directed to approve the change without testing. He asked me what I thought. I told him I was already running a test sequence on another product, and could run a quick test for the most severe problem the part might see, a 50 Volt short term transient Voltage spike. This "Identical, but lower priced" part, exploded on application of a single pulse. To check to be sure there wasn't an anomoly, I set up another sample with another 15 cent part, reapplied the pulse, which is quite common on 12 Volt vehicle electrical systems, but with a scatter shield, and wrecked another board. With the 85 cent part, I could hit the board all day long with the pulse with no problems. In the report, I did a financial analysis showing just 2 warranty claims without causing a vehicle collision would more than wipe out ANY cost savings over the anticipated production life of the base product. The lead engineer did further research showing we could have expected at least 40 of these failures PER YEAR.

We did not make the change. The 85 cent part remained in the production feed. The MBA was mad at engineering because she didn't get the $2500.00 bonus for her idea.

When in doubt, either find out from someone who knows, or do the tests. Save yourself a bunch of time and money.

Krylon does well by itself if you allow a full two weeks of cure time. The metallic paints do not hold up well to fuel so should be avoided unless you put a clear coat over it. I would avoid its use without a fuel proof coat if you are running a 2 stroke.
