Paint

Post by Triumph-Legend »

Can anybody advise me of a paint that once applied and dried does not disolve with petrol?

I have experience of spraying cellulose, 2 pack isocyanate and various enamel paints. The modern water based paints both professionally applied and using a rattle can air drying variant are useless, any contact with fuel and it will either disolve or lift of from the surface.

The only option seems to be to use the old iso 2 pack. :headbang:

I have had tanks resprayed by professional body shops and tank repair specialists lose their paint on contact with petrol.

Hi

It's the ethanol that's the problem, got my pedant's hat on ;)

You could always think outside of the box, I powder coated my last restoration's bodywork:

Failing that it's old school 2k / epoxy.

I carry tissues and wipe off any refueling spills immediately as a matter of course.

I sprayed my tank with 1k paint (with a spray gun) and went over it with aerosol Hycote petrol resistant lacquer. I haven't had a problem with petrol so far.

When I re-sprayed the last AJS tank, I used a black base coat and asked the paint supplier for a petrol/ethanol resistant lacquer. They sold me a 1 litre pack of lacquer, hardener and thinners, this was made in Egypt, so with full mask with carbon filter I sprayed it outside! This is dangerous stuff. Yes it was resistant to E5 petrol.

Tried this, or rather a profesional restorer of motorcycle petol tanks did a paint job this way. Fine until the slightest amount of fuel gets under the edge of the lacquer at the fuel cap or tap areas. The lacquer will lift, the base coat will then be destoyed and unless you are very lucky the whole tank will need repainting.

I'm coming to the conclusion that the best option is probably 2K base and clear lacquer as the only safe option.

You think I'm going to risk battery acid as well as ethanol on the paint you're having a laugh.

Just a quick bump to see if there are any new thoughts on this paint issue. :?:

To be fair, I think some sort of result from this question would benefit quite a few readers restoring their bikes.

I've found that Tekaloid and Tekaloid lacquer works fine for me as long as you don't let the petrol sit there.

The only tank I have had painted was taken by a friend to his car repair workshop where a lacquer finish was baked on. It is highly resistant to fuel but the only problem was that a couple of the waterslide transfers I applied blew small bubbles in the heat. No trapped air visible but there must have been some. Fortunately it was in the M of a flying M and could easily be spotted in with some silver paint. 8 years of messy and regular fuelling (only a 2 gallon tank) and no paint problems.
