We spray Magna Max pre cat and CV, hand sand between each coat, is anyone familiar with the surf prep system and does it work well for the in between sanding of coats? Is there an issue with sanding thru the previous coat? Any answers appreciated would like to speed up the finishing process. Paint finish = 2 coats of clawlock and 3 coat of magnamax. wood finish= stain, 3 coats of satin magnamax.
I have used the Surf Prep for couple years now with MLC waterborne products. It has worked great. Just make sure you let the product dry properly. I have seen it demonstrated on other MLC solvent based products and it worked great.
I would never go back to hand sanding it has saved me a great deal of time. Once you try it you will be amazed.
Is this system much different than putting a thick interface pad on a festool sander? I really do not want to get into air sanders. I have enough money in Festool stuff already. I am a painting contractor, so need stuff that works well in the shop and in the field.
There is an electric Surf Prep now. I too would rather use electric over air. But The electric wasn't available at the time I purchased.
I too am highly invested in Festool. I use it for everything except sanding between finishes. I spray only waterborne precat Lacquer. I tried most every combination with the festool sanders and just couldn't make it work for me. Then my supplier stopped by my shop and wanted to demo the Surf Prep for me. I bought it that day.. It is so easy and fast. And best of all the sanding pads don't clog. Unless of course you try to sand too soon.
If I understand it correctly, the "electric" version includes an air pump that drives the sander? I was looking at the 3x4 version. So, it really is still an air sander? Is this correct?
I am thinking of using one for scuff sanding in-between coats during the finishing process. Specifically for flat panel (AKA Shaker style) doors. A round R/O sander cannot get into the square corners on the flat panels, of course. BTW, the cabinet doors that I am sanding are quite large, almost the size of walk doors. Hand-sanding is not working well for me.
I would prefer an electric sander. According to the Surf Prep website, their air sanders would consume a bit more air than I have available. Or, at least the compressor would be running almost constantly.

WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.
Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).
Libel: Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.
Improper Decorum: Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).
Advertising: The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).
Repeated Forum Abuse:
Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.
There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).
