Mike T Posted August 15, 2020 Share Posted August 15, 2020 I'm repainting a vintage type with "Guild" aerosol enamel (sold to me as Flair Spectrum paint) which claims to be fuel proof. I don't want to go through the mess of cleaning this off and doing the job again at some point in the future, so I want to do a 'belt and braces' job by fuel proofing over the areas which will get oiliest - in and around the cowl, and where the exhaust ejects alongside the front fus and over the undercarriage. What have people been using lately - any recommendations? Quote Link to comment Share on other sites More sharing options...
Engine Doctor Posted August 15, 2020 Share Posted August 15, 2020 The spectrum paint s an enamel type paint so anything you apply over it must be an enamel type fuel proofer. 2K acrylic clear coat will probably pickle it although if allowed to cure for a long time you might ,just might get away with a very light coat. The spectrum is supposed to be highly fuel resistant provided it is allowed to cure properly, probably a couple of weeks before being exposed to fuel. The best single pack fuel proof paint IMO was Solarlac clearcote, sadly no longer available . Even that is not compatible with the Flair/ spectrum type enamel.

gangster Posted August 15, 2020 Share Posted August 15, 2020 The only fuel proofreads I have really trusted is the two pack type. Originally tuff coat / furniglass and more recently aerocoat. Had no problem using it over Flair or Humbrol unless applied too soon. The only paint I found it was not a success with was Halfords car touch up. It didn’t wrinkle it it just peaked off like sunburn Quote Link to comment Share on other sites More sharing options...

Mike T Posted August 16, 2020 Author Share Posted August 16, 2020 Thanks for the inputs everybody. I was gifted some Aerokote but I'm reluctant to use it as the hardener states a shelf-life of only 6 months and its way older than that. The Rustins sounds good, but as the paint is well-cured (about 4 weeks) I'm inclined to just key the critical areas with wire wool and coat them with epoxy finishing resin.

Andy Stephenson Posted August 16, 2020 Share Posted August 16, 2020 I read reports that epoxy as a clear-coat always yellows with age and particularly in sunlight. This may not matter if there are no white or light colours though. Quote Link to comment Share on other sites More sharing options...
Mike T Posted August 16, 2020 Author Share Posted August 16, 2020 The hardener in the Zpoxy I'll be using is already quite brown, but I'm hoping that won't matter as its going over a very dark black. (I'll try it inside the cowl first...) Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted August 16, 2020 Share Posted August 16, 2020 Sadolins PV67 is excellent as a fuel proofer but ain’t cheap. Quote Link to comment Share on other sites More sharing options...
Mike T Posted August 16, 2020 Author Share Posted August 16, 2020 Assume you mean the 2-part epoxy, Roy? I can also see 1L single part cans also being advertised. Both are described as "PV67", confusingly... Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted August 16, 2020 Share Posted August 16, 2020 Yep, 2 pack, available in 1 or 5 litres, can be sprayed. Quote Link to comment Share on other sites More sharing options...
Andy Stephenson Posted August 16, 2020 Share Posted August 16, 2020 Rob does it have to be thinned so it can be sprayed and if so what with. A. Quote Link to comment Share on other sites More sharing options...
