Topic: Engine paint , use primer before ??

[mhubert89]

hi ,

i am repainting my 68 289. Did you use a primer before spraying the blue color ? If yes, wich one is better to apply before ?

thanks

Yes, you should use primer, catalyzed epoxy primer would be best, followed with catalyzed paint within 48 hours.

The key to how well it holds up is how clean the surface is.  Absolutely all oil/dirt must be removed.

The best approach notwithstanding, would primer really have been used originally?

No - and never used it. Fills in allot of the small details and adds to that "dipped in blue plastic" look we often see on "restored" cars

I would use a non-catalyzed primer, and don't soak it. However, as pointed out; It has to be absolutely clean. Don't use something like POR. It won't come off and it doesn't deal well with UV or heat long term. I have used "bomb can" ceramic Corporate blue with the same gloss clear coat. It actually seems to hold up rather well if the engine is tuned well, even on a big block, where the exhaust exits.

I have painted engines without primer and spray cans, usually have to touch them up on a regular basis and the spray can paint is more susceptible to coming off if gas comes into contact.  Guess if you don't mind touching up, then go the quick/cheap way.  Agree that some detail can be covered over, but only if thick heavy coats are applied.  The engines I've done with primer/catalyzed paint hold up very well.

Charles, I like the look of the two stage, but it's only rated for 375 degrees. FE's burn much hotter than that at the exhaust flange, and that is were most of the issues come into play with touch up.

There are 100's of engines in driver cars using the 2 stage - BB's included that have been in use for some years now. I have yet to hear of problems that are even close to those experienced using the so called high temp rattle can engine paint. That is why most knowledgeable professional shops and experienced enthusiast restorers use the PPG engine paint product. That is why I wouldn't be afraid of it.

It should be blue, the pulley was semi-gloss black and installed as needed, single, double etc.

Small block oil filter surfaces (gasket) was masked off with some slip on mask. Like the radiator hose necks, PVS, heater hose connections, fuel pump gasket surface ... Most are shown in the Boss section of the site where I showed a Boss engine I painted. Very similar details

Engine was painted before the balancer was installed - it was painted semi-gloss black by the supplier/provider
