Re: paint lower unit
ok, getting the etch primer and zink chromate and johnson white tomorrow - looked up the description on Acid#8: don't
"Under normal circumstances it is not necessary to flat ACID #8 and can be directly overcoated.
ACID #8 may be overcoated directly with top coat.
However, if the repair requires additional build primer filler should be used before topcoat is applied."
Do you agree I can skip the zink chromate? Or should I use it?
Stop, don't buy anything just yet! :attention:
Not knowing what type boat you have (fiberglass or aluminum) you don't need both Zinc Chromate and Self Etching primers. Usually one OR the other.
If your hull is fiberglass, you don't need either one of those primers. So for fiberglass use a good quality filling primer (usually called High Fill) and then you can sand it to a very smooth finish before applying the paint. If you have an aluminum hull, pick either Zinc Chromate OR Self Etching primers for the first coat and then follow that with again the high fill regular primer and sand to a very nice smooth finish before applying the paint. If you have some serious gouges or deep scratches, those will need filled and feathered and primed as well...
The actually finish will be determined by the primed finish. If you take your time and make the primer finish very smooth and clean, then the paint finish will look amazing as well. Paint doe not cover any imperfections in the primer finish. If you can see it or feel it, it will be most obvious when you apply the paint...
