After that I went to local boat works yard and talked to pros. They said that they spray everything with HVLP even tho Interlux told me it's not the way to go. I did try airless gun as this is what Interlux recommend and it was still to thick. After sanding and trying all ,,factory recommended methods,, i went with HVLP and 1.7 tip for great final results. BTW do not fallow their wipe with thinner before applying another coat recommendation. It just bubbled up my last coat. Good tack cloth ,, Ideally with no wax'' is all you need after sanding every coat. If I had to do it all over again I would go with automotive finish since you can't buff Interlux and primer is terrible to sand. Prep work is key to any finishing project. Take time to take off all parts off the body and mask tape what you can't.
Wet sanding is the key factor for good results.
I thought all was lost for my paint
job until the light
bulb went off in my brain to use water as a cutting fluid for sanding the primer. As in it really likes be wet sanded and when you do it that way it does not clog up the sand paper. Once I figured that out the job was much easier. It would be even easier if I had a "wet random orbital sander" except that the surface of my Campster
is far from being flat and buying a decent quality power sander is not in my budget but at least my elbows, shoulders and wrist still rotate randomly for now with the help of some Ibuprofen
For some reason the primer directions don't state to wet sand, I guess they figure they are selling to professionals who have that knowledge and equipment. That is how they do it at boat yards and also in automotive shops where they need to keep the dust under control.
also likes to be wet sanded.
So know that you know the secret for sanding it you won't have to be nearly so frustrated with the process.
