Unknown original paintwork - Posted: 20th Oct 2010
I'm In the process of restoring a 34" Fireboat that I acquired off ebay.
Unfortunately when trying to spray on an acrylic primer I'm getting an adverse reaction In that the new paint Is bubbling / crackling In some areas. I have no Idea what the original paint was although It looked to have been brushed on.
Any Ideas please for a suitable protective and Inert primer / undercoat that I could use to stop this reaction.
Many thanks

HI Chris
I have read the Info sheets on both the products suggested. A clean solid surface Is required for both so If like me you have already damaged the subcoats then you will need to wet and dry to a firm surface. This was my problem, and I suspect yours, as the subsurface was rubbery and absolutely refused to set or sand to a smooth surface. I,m sure both products will protect a good prepared surface before any other paint Is applied, but I suspect neither will rescue a damaged surface. It will be Interesting to hear how you progressed.

I've not yet experimented with an airbrush, so have brushed the first coat on today, It looks like It will need a further coat to cover It reasonably. Will let you know how It goes.

You can paint laquer over enamel ,but I would suggest going back to the base wood.Use a primer sealer to seal all the other paints out then go from there.I know what your talking about,happened to me till I figured out how to deal with it.Ive even gone as far as to brush on a couple layers of 30min epoxy deluted 50% with denatured alcohol to use as a sealer then start my primers to get smooth.Do Not Paint Enamel over Laquer,the enamel takes a long time to dry which attacks the under layment of any paint/primer.This is why the bubbles form under the paint you just put on
