Thread: advice on sandpaper grit

Tweet

Thanks SprayTech could I use an aresol type primer for the (guide coat)? and if so what would you rec. I use? I have some spray equipment and a 60 gal compressor but I think that I would rather just get the body work done and get it to a painter to have the base and clear done. The area that I build up should I buy some ppg D90 and respray those areas? Or again could I use some sort of arisol can primer? like I said I have never sprayed is it possible to prime outside with just a respirator? the reason I don't want to paint is well two reasons one I have never done it before and two I have heard that you really need a good booth and a fresh air hood so not to kill yourself.

thanks,

Yes an aerosol can of light colored primer will work as a guide coat . This will show Highs & Lows when you run a block over the panels .
Sanding in an X pattern as it will not cut groves the size of your block in the panels Use this method through every blocking process !

I would not use a spray can primer for priming your body work , use PPG's K36 for your priming & blocking process , and I would stick with PPG products as this is what your ground surface is , I am not a big believer in mixing products as you never know what is or is not compatible with each other . Even though many mix products with great success .
It may take a few primings and blockings to get it ready for paint .
PREP work is 80% of a paint job .

When you have it ready for paint I would leave it in the K36 primer and let the paint shop use the sealer and base coat and clear . Hopefully finding a shop that shoots PPG .

SprayTech sorry don't mean to be a pain in the A** but one last question, I have been reading up on saftey of painting, I read that a active charcoal face mask is actually sufficent is this true? Here is my plan and I want to know if you think this and a face mask respirator would be okay not a risk to my health since I already smoke cigs. I am buying a 20 by 30 protable car port to put in my back yard ( large yard) and store my 1992 mustang that lost its place in my garge to the 29 model A. I was going to get a 20x30 tarp and errect the fully enclosed car port over it. I thought I could make some sort of houseing out of 2x4s and plywood that could house 2 box fans about 2-3 feet off the floor, and put that in the entrance way closing the front of the carport on it then have the fans blowing in with house hold a/c filters on the front of the fans, then have the back door of the carport 1/2-3/4 open. do you think this would be an okay enviorment for painting and a safe one with enough ventilation and use of only a carbon filter face mask?

thanks,

I use the 3M Charcoal respirator every day , but make sure you get one that fits snug to your face and seals ( S, M & L sizes ) , can NOT be used with facial hair ! Mustache is ok but not goat -T or beard .

I also use the 3M full face Charcoal mask too , uses disposable charcoal filters that can be changed when needed ( and you can buy to replace them ) , and I buy a package of tear offs to keep the lens clean of overspray . I like it better as these high solid clears bother my eyes , and Isocyanates ( catalyst or hardners ) go towards moisture
With these masks , make sure you seal them in a big zip lock baggy to help make them go farther as once they are opened they will filter air constantly and therefore reducing protection & made useless .

Any one of these will work for a person that doesnt spray all the time & everyday . No need to purchase a high dollar fresh air unit for a few times spraying . I have been breathing this crap for 30 years and havent died yet , but the lungs dont have the capacity they once had and I dont have 3 arms or 15 toes , and not bald ........ ha ha ha
