Paint Information
     This paint is Alkyd Enamel. Its finished appearance is identical to the Lacquer and Acrylic Enamel that these motors were painted with originally.  This paint is manufactured by R.M., and is from their Limco 1-2-3 line. Alkyd Enamel is Limco-1.  
 
     The reason for choosing this paint has to do with hardening. The hardeners in all types of paint work anaerobically.  This means that they harden without air. Once you add the hardener to the paint it hardens in about 3 hours no matter where it is, even in an aerosol can. This is why you can't add hardener to paint in aerosols.  It is also why most commercial paints available in aerosols have such poor durability.  Without their hardener most paints reach a relative hardness (compared to hardened paint) of about 20%.  The one exception is Alkyd Enamel.  Without hardener it reaches about 80% hardness.  So even out of an aerosol can you get toughness and a gas-proof finish.  
 
     If you are going to buy bulk paint you can buy the hardener and reducer locally at an auto body supply shop ... just call around to find out which ones sell R.M. paint.  The hardener is LH-100 and the reducer is LR-12.  If you have trouble locating a source close to you, call 1-800-825-3000. This is the BASF help line. They can help you find the closest dealer.

NOTE 1The mixing ratio is 8-1-4, paint-catalyst-reducer. If you use the Alkyd uncatalyzed the ratio is 4-1, paint-reducer. The mixing ratio for the Urethane is 8-1-4, paint-hardener-reducer.

NOTE 2:  Though Alkyd Enamel is the hardest paint available in aerosol form, Urethane based paint is the hardest known paint when it is mixed with hardener.All modern cars are painted with Urethane based paint. For those who would like to get the most durable paint job possible, all my colours are available in Limco-3 Urethane. Unfortunately the cost is 25% higher than Alkyd and the hardener is 50% more expensive than Alkyd catalyst.


Decals
     If you are applying vinyl decals you don't have to do anything special, the glue on the back of them will stick to just about anything. However, if you are applying water-release Lacquer decals you will have to buy a glue to get them to stick to this paint properly.
 
     Manufacturers like Mercury, Johnson and Evinrude all used a glue to hold the decals on when these motors were made.  However, because they all have used vinyl decals for at least 20 years they no longer sell these adhesives.  You can still buy them from most hobby stores. Several different manufacturers make these products.  One type is an adhesive to glue down the decals and the other is used to shrink the decals to help them fit around compound curves, so you don't get them wrinkling at the edges.  The reason for all this trouble is that water-release decals don't come with glue on them.  There is a water release compound on the paper backing some of which stays with the decal, which will act like a weak glue on soft paint surfaces, but it is too weak to work on the smooth hard surface of this paint.
