Spots in sealer

aafadca · 03-06-2010, 11:02 PM

http://cid-987e971f435ad2a9.skydrive...m/P1000237.JPG stripped most of my car (with the razor blade. It worked for me!) But a lot of the paint had "bubbling/pimples" over a lot of the body. When I stripped it, I found the gray sealer had a tremendous amount of dark spots/speckling in it. I'll try to download some pictures if I can. In the meantime, does anyone have any ideas before I take it to the painter? Thanks in advance

Do not worry about it. Just make sure that all of that layer os sealer or whatever it is is removed. Those spots can either be from moisture being trapped when the product was applied...and it may not have been alllowed to "flash off" long enough and trapped solvents. This is especially true if it is a lacquer primer and the painter who shot it "pounded it on"...instead of applying several coats with goods flash time between coats.

Multiple thin coats is always better than one heavy coat.

And by the looks of your photo....it appears that they used some old "red cap spot putty" and some of the light blue crappy filler also. More than likely it is lacquer primer.

Do not be concerned...as long as who ever is doing your car uses the products to seal your body...so you do not have any issues with future blistering/bubbles. Many views on this topic here on the forum...on what to apply on your body first. And those views may or may not be what your painter is willing or capable of doing correctly....or if he/she even knows that there is a potentential problem with your body due to being made out of press-molded fiberglass.

Thanks for the info. I feel a little better now:-) I was also thinking maybe some type of moisture. So you think I should go ahead and "scrape" off the sealer now or lae the painter finish it?
Thanks again for the info

I seriously doubt that you are going to be able to scrape any more off ...once you get down to the primer/sealer coats. Those will need to be removed....either by chemical stripper, media blasting or sanding it off. I would not recommend sanding it off due to the skilled labor that you are planning on using BETTER know what they are doing VERY WELL when it comes to fiberglass bodies. And goes the same with chemical stripper and or media blasting. I am not a fan of the soda blasting...but that is just me. I do all stripping in house and use chemical stripper....but then again I have been doing it for over 20+ years and know how to use and respect the chemical stripper. I hope that teh shop that you are using knows about the press molded fiberglass. And whatever you do...make sure that you inspect the car BEFORE they apply any product(primer/filler,etc) to the stripped panels...so you can see that it ALL has been removed.

Best of luck,
