……………….. the reason for undercoating was two fold...to eliminate water wicking its way into the body and as Phil mentioned, causing the paint to bubble, and also to help reduce drumming - where the body would resonate at speed...…………
I read something somewhere about the Aero drumming, I think the rear quarters & doors. Doors skins had some sort of coating, & I think a bracket was added to the quarters.
Glasspar made boats long before they made car bodies and boats would be absorbing water all the time that they were in it. Were the boats treated with something to protect the boat from water damage?
Glass boats stored in water were susceptible to blisters or "boat pox" until fairly recent years when a more impermeable gelcoat became available. Water passes through the gelcoat by osmosis and literally forms raised water filled blisters between the gelcoat & underlying fiberglass. Expensive to strip & replace, and the underlying glass must be allowed to dry before recoating.
It has been primered, painted and clear-coated with no regrets. ………………………….
I agree wholeheartedly. Almost every piece of my car has been cleared with one sheen or another, even NOS enamel parts. Just gives another layer of protection. Not according to Hoyle but after all the work, I could care less about that aspect.
Alternately, the painter was finishing up a 6 figure mustang when my body came in for paint. Correct in every possible detail, including "natural" metal parts certainly destined to rust sooner or later.
