Primer
« on: October 21, 2016, 09:07:11 AM »

I've had some problems with the final coat on my wooden hull. Used exactly the same technique which has worked for me in the past i.e. sand/fill/sand/detack/prime/sand/panel wash/detack paint. 99% of the bottom is fine but I had problems as shown in the pics.





Anyhow, I've stripped all the protection off and re sanded all the hull, in some places right through to bare wood. Can I re prime the whole hull over the top of a the enamel?

Neither Dave, Halfords don't operate in Australia, and not Plasticote

Geoff
The MSDS stuff on the primer indicates that it's based on acetone and xylene solvents. These are usually effective strippers of enamel paint, which is oil-based.
Sorry, mate, but I think you're going to have to strip the enamel off completely before you apply any new primer.
